Planetary Imaging

[hasty hull]

Very nice, similar to the best I was able to get in ‘23 with my 6” dob at 3600mm

Though I will say for Venus, your scope is surely capable of capturing good cloud detail with uv filters. Worth pursuing if you can get one

[terse night]

@somber stratus since I'm buying an imx178 for guiding (and that's mono too) do you think it would make sense to shoot luminance only on planets? Just because if I were to shoot colors I would be really limited in the amount of time I can image with each filter. I would get a very sharp mono image tho, there's pros and cons. What do you suggest?

[thick heron]

Luminance is not a good filter for planetary imaging. It is more sensitive to seeing conditions than individual RGB filters and you don't get a color image.

[terse night]

So I should shoot RGB only? How much time per filter? If it's needed I would be shooting with a C8 with a 2.25x Barlow. The camera could be a 533 or a 178 I have both

[terse night]

Also, wouldn't the time needed to swap filters be an issue?

[summer pebble]

They are indeed quite pricey though. How would IR pass filter do instead?

[livid sierra]

IR pass works, but you’re less likely to catch cloud structure in IR. Most of the cloud detail is in UV/NUV

Sometimes it’s visible in VIS

A W47 with a UV/IR Cut that passes around 380nm, like the Player One, can be used to image in NUV

Much cheaper than an actual UV filter, but of course there is less contrast in NUV. Also keep in mind, to really properly image in UV you need a mono cam. For NUV, an OSC cam can technically be used. But getting an actual UV filter without having a mono cam is a waste of money

[white prawn]

I'm sure that someone will correct me here. Planetary though is usually done in RGB only, most of us use UV/IR cut filter only unless they're doing something special/neat (Methane/IR Pass/etc). IR pass is good for lum; however, since rotation is a thing and can be quite evident on some planets (ahem - Jupiter) the focus is on RGB to get detail. IR can give some enhancement but it's usually a single bit out of a few images.

Or if @livid sierra is contradicting me then listen to him. 🤷

tl;dr my thought is focus on RGB, but filters can get good data, I haven't finessed using more than UV/IR but I imagine the way planetary is done time between filter swaps wouldn't be too much of an issue anyway in spite of planetary rotation.

[terse night]

I would also eliminate CAs shooting RGB right?

My main question is how much time I should image with each filter. My guess is like 40 seconds at most but I've no idea

[white prawn]

Are you imaging by long exposure photo or video? Planetary is done by taking a short video with exposure set as short as possible (I set my exp at about 9ms and gain to compensate). Vid for about 1.5 min. So a couple of vids with UV/IR cut, then one with another filter (all I have rn is IR Pass)

I've actually been thinking about that to work a IRPass filter in a Jupiter imaging session. I usually do 10 vids at a time.

[livid sierra]

W/o filter?

Are you imaging without your uv/ir cut again?

[hasty hull]

Bro

[white prawn]

Ha! Nono, I meant with UVIR, w/o other special filter. Good gravy, that Saturn image was enough shudder

[summer pebble]

Sounds promising. I’ll check out the W47 as I don’t have a mono cam with me

[terse night]

I'll shoot video. Isn't an UV/IR cut just a luminance filter? The one I have literally only allows visible light trough so that's it?

[livid sierra]

It’s essentially the same. But if you’re going to image in mono with an L filter then you’re gonna need an ADC just like you would with an OSC cam, or the image will look blurry due to atmospheric dispersion

The ADC would still benefit even when imaging through RGB filters

But if you don’t mind having no colour in your image, then just image through an R, G or B filter instead of L, because there’ll be less atmospheric dispersion through individual filters

R will have the best seeing, B will have the best resolution but needs good seeing. But they will look very different from each other obviously

[white prawn]

If you are using a mono camera, you'll need to use the filters individually. The time it takes to swap the filters between videos will not be an issue since it shouldn't be more than maybe a minute or two; less if you have a drawer. Keep in mind when I say that I am thinking that if I were doing mono and using filters, I'd shoot one video with one filter, change filter, then shoot another, then do it again.

[terse night]

I have a filter wheel

But how much video time should I get per filter?

[white prawn]

I'lll honestly say I'm not sure

[terse night]

Cause people told me 3 minutes with osc is barely okay, if that's the case tho I'm forced to do less than a minute per filter

50 seconds assuming I can switch filters in 10

[white prawn]

I image for 1.5 min with my 585 in OSC, and that's not an issue. It does make sense that filters would require less time. Tom has done some absolutely fantastic stuff to the point that we think he's just deleted the atmosphere over his house. He will take a couple of minutes between images to defrost his mirror if he has to, and his derotated images are incredible.

tl;dr don't worry about the inconsequential amount of time it takes to swap filters.

[terse night]

I'm guessing winjupos is the way to go then

I guess I'm gonna try a lot of different things

Like 30 seconds per filter, one minute per filter, then 2, and so on

Also my camera does 60fps at native resolution so with the correct ROI it's gonna be very fast

So I can get away with less video time

[white prawn]

My best image came from me doing 20 individual images, doing a quick preliminary process, then sending them through WinJUPOS.

This is how it came out

[terse night]

Only 20 images? I'm no expert but I'm pretty certain thousands of frames are gonna outperform 20 single images every single time

[livid sierra]

He means 20 stacks..

[terse night]

He said individual images so I thought he meant individual exposures.

[white prawn]

I took a shortcut, and got lost in translation. Sorry. Duif is right, I did mean 20 individual stacks. Each stack was processed out of a 2 minute video. I think the only thing I really could have done different is a little more denoise maybe.

[long rune]

Oh my gosh

Fire dude.

[white prawn]

What do you use for stacking? There's a bit of a "halo" artifact around Jupiter that I associate with WinJupos doing its thing, is that what you used?

@summer pebble this is what I got out of just one of the stacks.

[summer pebble]

I use autostakkert for each capture and then winjupos for each stack

I’m not entirely sure where the artifact arises from

[white prawn]

Huh. I use SharpCap to capture, AutoStakkert to stack. From there, AstroSurface. For me, WinJUPOS is for when I'm derotating.

[summer pebble]

Ah, perhaps I was too unclear. My process is firecapture to capture, autostakkert to stack, registax for wavelets, and then i use winjupos for derotation.

[dark cargo]

Garbage everything on my and the atmospheres part, however I managed to get this pretty interesting moon arrangement at around 10:15pm AEDT today:
Callisto up top, Ganymede on the right and Io transiting Jupiter below both

[livid sierra]

Lucky arrangement, nice

[cloud copper]

Does anyone know what my fl will be after I’ll add an omegon Adc? I currently have a native fl of 1500mm and a 2.5x Barlow

How much will it increase

[livid sierra]

It’s kind of a gamble

It depends on the specific Barlow and additional backfocus of the ADC

But probably I’d count on the ADC making the Barlow magnification ~3.5-4x

[terse night]

@livid sierra . With my C8 and the imx178 what power Barlow should I get? Also, what Barlow brand to you suggest? I'd probably go for TeleVue cause they everything they make is good but I don't know.

[livid sierra]

For good sampling you want the focal ratio to be at 5-7x the pixel size, so that’s f/12-f/16. Because the C8 is at f/10 you would need a 1.5x Barlow, but those aren’t as common as 2x or 3x Barlows

So you could stay at f/10 and be a tad undersampled, or look for a 1.5x Barlow, or just get a 2x and be a little oversampled

And yeah Televue is good, or Celestron X-Cel Barlows have a good reputation too and are a little cheaper

[terse night]

Good to know, I actually have a 1.3x Barlow so I could use that

I also have a 2.25x one and I could use it for the imx533. With that the ratio is 6

[cloud copper]

does anyone know why my derotation looks like this?

[livid sierra]

What are the timeframes of the stacks and what time did you use for reference timeframe

[cloud copper]

whats a timeframe?

i usually just put the stacked images and its fine

[livid sierra]

Move the image window and send another screenshot

[cloud copper]

here

fixed it

[livid sierra]

Cool

[cloud copper]

here is the image

looks ok

[unkempt igloo]

Very nice mate

[main flume]

hewo

[main flume]

snazzy

[white prawn]

Anyone have tips for photographing ... or maybe processing ... Jupiter's moons?

I may or may not have taken a few images without Jupiter but involving Callisto; then Io, Europa, and Ganymede.

[gray orchid]

Didn't even bother with a Barlow as seeing was ass

[silk sentinel]

Is this raw with no editing? I took a video but I cannot figure out how to process it

[main flume]

autostakkert

[silk sentinel]

My problem is that pipp gets confused by the moon and mars and doesn’t know what to stabilize and my video is a .mov cuz I don’t have an Astro camera

[main flume]

just dont use pipp???

[silk sentinel]

Is there an app to transfer the video to an avi

[main flume]

not that i know of

[hasty hull]

You can just use PIPP without any of the processing features, just load the video in and set the output to avi

[silk sentinel]

Thank you

[astral zenith]

My first attempt at an HDR moon

Not that sharp since I have a cheap lens

I use GIMP

Is it good?

Or mid

[left spindle]

good

[astral zenith]

Yay

[left spindle]

ill try to sharpen

do u have the stack?

or processed tif file?

[astral zenith]

Yea its on my laptop

Stacked best 150 frames of 600

[summer pebble]

Jupiter along with Io and Ganymede

I may or may not have forgotten to use my uv/ir cut filter...

[main flume]

yummy

[summer pebble]

I did not forget it this time

[terse night]

Nice

[white prawn]

Jupiter Jammin

Mine don't rotate like that, how'd you do that? Did you reposition or just imaging for a while?

[main flume]

With a little sacrifice

Jammin' 'til the jam is through

We're jammin'
To think that jammin' was a thing of the past
We're jammin'
And I hope this jam is gonna last
No bullet can stop us now
We neither beg nor we won't bow
Neither can be bought nor sold

(jamming by bob Marley)

[summer pebble]

Oh I simply put 10 two-minute captures (after processing them) through pipp and used the gif output option

[hasty hull]

Think he means the field rotation, looks like you were imaging as it reached zenith

Alt-az moment

[summer pebble]

ah, in that case 100%

i am without an eq mount unfortunately

[white prawn]

Aha

This should make for interesting imaging if I ever get my Nexstar up and running.

[zenith nimbus]

Oooohh

[summer pebble]

Planning to target Uranus

What’s a good histogram like for the planet?

[low tendon]

second time for me ever doin planetary, heres the data if anyone wants to play with it and also heroic frog's process of my data

[white prawn]

I'll play

[low tendon]

WOAHH Great process!! personnally id sharpen a lill less

[white prawn]

Yeah, I used the settings that I work with on Rio (my 8") to work with the image from your 6".

[white prawn]

Nice work. When can we get your seeing conditions?

[rugged knoll]

sacrifice a powerseeker

[zenith nimbus]

Gips on getting bettef?

[left spindle]

Lower your exposure(not too much or ringing artifacts may appear)
Barlow up
Get more frames and choose best 100-2000 frames depending on your camera noise
For jupiter, a stack must not exceed 2mins (realtime) it smudges the surface detalis

[wispy pagoda]

Hm I took a look at damian peach's pickering scale and it looks like i never got more than a 4/10 since I got my 10" and my average seeing is around 2/10...

[white prawn]

Last bit may depend on camera; with my DSLR I was doing 3m and it didn't appear to smudge but that probably had to do with the level of detail it was able to capture.

Nonetheless, all correct.

[hasty hull]

I’ve had about two nights of like 7/10 seeing this season, been rough going for us

And those were only small portions of nights as well

Hope we all have better luck this coming season

[south nest]

Does anyone know how to download Registax or have a download link? The download link on their website doesn't seem to work, I don't think its something with my computer but it is entirely possible

[fading plume]

Use astrosurface, or wavesharp I think it’s called. New thing from registax developers

[white prawn]

Going to recommend astrosurface. I used registax, then moved to Astrosurface, my processing started coming out better partly from what I learned and partly from using a program that was easier for me.

I have tried WaveSharp and .... um. I found it to be more of a WTFI instead of a UI and couldn't get anything out of it.

[south nest]

Thanks!

[low tendon]

yo, i shot jupi again, this time with a lil better seeing, could u pls process it the same way u did the other jupi stack?

(the image is unprocessed)

[left spindle]

i gave it a go

def could do bettet

[woeful obsidian]

Great process but y is there a wing around Jupiter

[terse night]

My attempt, very fast so it sucks

[woeful obsidian]

No sharpening?

[terse night]

Tiny amount, I'm still lerning how registax works

[woeful obsidian]

Like the colors

[terse night]

Every time I sharpen it looks too aggressive to me

[woeful obsidian]

I tweaked calcuphers process a bit

[lament turtle]

The clouds have been tormenting me for days now and i had a desire for processing images so i tried my best on this one

[terse night]

Why do your colors suck so much

Do you even do an rgb balance?

[woeful obsidian]

I clicked on it when stacking in autostacker

[terse night]

Yeah, you need to hit autobalance after that

This is the result after rgb balance only, there's nothing else applied

Colors are already way better

you need to do an rgb align as well

[livid sierra]

Use small scale wavelets

[terse night]

Guys I still don't have a reducer so I cannot do DSO but I can do planetary, my question is: since my guide cam is gonna be the one I'll use to image, how do i track planets with nina?

Cause I'd like to automate the rig to create a timelapse

And if I don't polar align perfectly I might lose the planet, my fov is pretty tight

[terse night]

@livid sierra @somber stratus is this even remotely okay for planetary? My sensor is very very tiny so even tho it's not an apo I don't think CA is gonna be a big issue (imx178) https://www.astroshop.it/lenti-di-barlow/baader-lente-di-barlow-2-25x-1-3x-q-1-25-/p,33612

[zenith nimbus]

Is that saturn?

[low tendon]

yes, yes it is

[dark cargo]

I've looked into getting it before and I don't think its the best option. Omni 2x seems to be better even through its much cheaper?

This is one of the only barlow comparison documents that I could find: https://drive.google.com/file/d/1K3wkihKAZt_NoFcEkadG1_R0EAKzj3dG/view

[rugged knoll]

i was told svbony ones are better than the omni

the apo ones, not the ultra cheap ones

[dark cargo]

Those are GSO rebrands I think?

[rugged knoll]

whatever they are they are very cheap for their quality if it's really that good

[high hull]

yeah the celestron 2x omni is perfectly acceptable in my experience

[white prawn]

https://tenor.com/view/unicorn-adri-summon-summoned-i-have-been-summoned-gif-22384832

[white prawn]

I adjusted my settings this time.

[low tendon]

Woah thanks you so much man

[terse night]

I could basically drop the Barlow then, I have 2.4um pixels and at 4500mm I would be oversampled. I can use the 1.3x Barlow, that should perform better

[rain mauve]

This is my jupiter with my phone and telescope

Does it look good?

Telescope 80mm with 900mm focal length and use 10mm eyepiece

[terse night]

@somber stratus I need some help for planetary, I'm gonna try for the first time today. My Barlow is not that good but I can make it 2.25x or 1.3x by unscrewing one glass element. I have two cameras, one is the main camera with 3.76um and the other is the guide camera with 2.4um. What combination of camera/Barlow should I use? The 2.25x with the 3.76 would be a pretty good sampling but I'm worried the Barlow is not sharp enough, is using the 2.4um pixels with the 1.3x Barlow better to make the quality of the Barlow less important?

[thin aspen]

I think he explained once that Barlow quality doesn’t actually impact the image quality at all as I believe seeing is generally the overweighing limiting factor. I think good barlows are inly noticeably better when there is good-excellent seeing. Could be wrong though.

[white prawn]

Your seeing will be biggest limiter. Personally I’d use the camera with smaller pixels as that can capture greater detail. Unless your Barlow is absolute plastic junk it likely won’t make an overall difference on the image.

[terse night]

I'll send link to the barlow

https://www.astroshop.it/lenti-di-barlow/baader-lente-di-barlow-2-25x-1-3x-q-1-25-/p,33612

[white prawn]

It’s not one that I personally would get but the important thing is that the lenses are glass. Should be fine to use with 2.4um pixel camera

At either magnification

[terse night]

So you think that with 2.4um pixels and at 4500mm I'm fine? Seeing is really gonna limit but yeah

At native resolution...

[terse night]

This might be too much magnification

[white prawn]

Yep! Seeing will be the biggest challenge

Eh, try it

[terse night]

I can always unscrew the extra glass element and use it at 1.3x if i see seeing is limiting too much

[white prawn]

Worst that can happen is that you look at it and say, “well that didn’t work out”

[terse night]

Yeah that's what i like about planetary, it's easier to try multiple things out

[rugged knoll]

So i don't need an apo barlow?

[terse night]

It probably depends on how big your sensor is

[rugged knoll]

11.2x6.3mm

2.9um pixels

and 750mm fl

[terse night]

Even non-apo barlows correcto for cromatic aberration but near the center it's usally fine

[terse night]

imx585?

[rugged knoll]

yes

[terse night]

Yeah I think it's fine especially at 750mm

My sensor is 7.4x5mm😅

[terse night]

Very very small

[rugged knoll]

i want to get a new barlow to get 3000mm

[rugged knoll]

😨

[rugged knoll]

cause my current is only 2x

1500mm

and it's a cheap svbony

[terse night]

4x barlows need to be more expensive i think

[rugged knoll]

but if it really doesn't matter then ill probably get that cheap 5x svbony one

[terse night]

Because at higher power the fact they are cheap becomes quite evident, this is my understanding at least

[rugged knoll]

so what would you reccomend?

[terse night]

It depends on your budget

If you only care about performance Powermates are probably the way to go

[rugged knoll]

https://agenaastro.com/gso-5x-apo-barlow-lens.html

this good?

[rugged knoll]

i have absolute shit seeing always

so it doesn't need to be that good

[terse night]

If you have bad seeing there's no point in a 5x imo

I'd go AT MOST for a 3x

[white prawn]

For Barlow lenses, I've used the kit Celestron 2x, the Astromania 3x, Svbony 2x, and I switched my Astromania 3x for a Celestron X-Cel 3x. I can speak well for all of them.

also I do have an Orion 5x Barlow lens and that was most handy for imaging with my DSLR.

[woeful obsidian]

https://drive.google.com/file/d/1ArROohpJeEBCHt3LEfprNbgkvKOwTb5y/view?usp=sharing can u pls process one last thing for me, this is a jupi stack with red spot and better seeing

[white prawn]

Definitely not needed with a planetary cam

[white prawn]

Won't be immediate but I'm having fun with those. Prob tonight.

[woeful obsidian]

If u can pls try to process it exactly like this

[woeful obsidian]

Appreciate it

[livid sierra]

@terse night picking a camera pixel size doesn’t depend only on focal length but rather focal ratio as a whole

[white prawn]

@terse night what @livid sierra said and there's some formulae behind it. I mentioned smaller pixels for detail based on my setup, and I did presume similar setup or something for which the smaller pixel would be appropriate.

[rugged knoll]

4x is optimal for me

and since i don't see any cheap 4x i wanted to go for 5z

5x

[white prawn]

If 4x is optimal, then 3x will serve you well enough. If you get 3x plus ADC and learn how to use the ADC then that's near 4x.

Speaking as a guy for whom 4x is optimal as well, and am using 3x. I need to pick up skills with the ADC.

Speaking from experience, 5x is too much.

[terse night]

Yeah my native focal ratio is 10 so that would be 13 or 22.5

[white prawn]

The 13 focal ratio would probably do well with the 2.9µm camera. My 585 has that pixel size and my ideal f/ ratio is 14 I think (what brings my best Barlow to 4x). So yours is similar. Not sure what the 22.5 would be best at though.

[livid sierra]

Best option is probably f/13 with your 2.4um pixel camera

f/22 is pretty oversampled for 2.4um and undersampled for 3.76um

f/13 should do pretty good with 2.4um

What are the cameras in question? I’m guessing imx224 for the 3.76um one?

And again, focal length alone is pretty irrelevant when it comes to sampling, you need the focal ratio to make any useful statements about it. An image with your scope at 2600mm f/13 with the 2.4um will look quite the same as 3800mm f/19 with the 3.76um for example

[terse night]

imx178 for the 2.4um and imx533 for the 3.76um

[terse night]

So if I wanted to image with my 533 what Barlow works best? I'm guessing a 3x?

[white prawn]

I feel good seeing that your statement agrees with mine, thank you. I have no understanding on the formulae involved but I remember the specific numbers of my setup and they were close.

[livid sierra]

If you want to use the 533 you should use a 2x to be at f/20, that’s a little over 5x pixel size, or a 2.6x for f/26, that’s 7x pixel size, good sampling for blue light

But combining a 2x with a spacer like an ADC could also get you at f/26 if they go together

Depends on the specific Barlow and the length of the ADC

5x pixel size is good sampling for red light, but undersampled for blue light

[terse night]

Could you suggest me a good 2x Barlow and a good ADC?

[terse night]

Should I go for something in the middle or straight up get 2 barlows?

[livid sierra]

Why 2 barlows?

[livid sierra]

Celestron X-Cel barlows are good and any ADC would do the job. ZWO is good, as is omegon. Omegon is a little bit taller than ZWO

I use an X-Cel myself, they’re relatively cheap for their quality

I think the 2x X-Cel with the ZWO ADC would result in something between 3-3.5x

[terse night]

Two different barlows for two different colours, seems overkill to me

[livid sierra]

No

5x or 7x are both good, but most people aim for 7x so they are perfectly sampled for blue light in case excellent seeing comes along

It doesn’t really matter that red is oversampled then

[terse night]

Oh okay

[livid sierra]

Just aim for something 5-7x

[terse night]

With the 2.25x and the 533 I'm at 6x

Cause I'm at f/22.5

[livid sierra]

True

[terse night]

If I place the Barlow before the filter wheel I'm also slightly further from the camera so that results in more magnification (?)

[livid sierra]

But I thought you would rather want to image at 1.3x so you would only have to use one barlow element

[terse night]

Yeah because I'm worried about the quality of this Barlow

[livid sierra]

Correct, the filter wheel acts as a spacer

[livid sierra]

It’s your decision then

[terse night]

I guess I'm just gonna try a lot of things out

Should be clear almost all time tonight

Well thanks for all the help @livid sierra

[white prawn]

My $0.02 to this is that your Barlow should not be an issue in either event. Use the 1.3x with the 2.9µm camera, have fun.

Of course, don't take that to mean that I would discourage you from trying stuff out. I've done it and you're on track to try a few more things than what I've considered. 🤷 🙂

[low tendon]

what software u use to proceess?

[white prawn]

AstroSurface.

Followed by Gimp for final touch-ups

[low tendon]

ok

[tiny topaz]

Is astrosurface better than the pipp, autostakkert, and registax processing

[white prawn]

I still use AutoStakkert for stacking. Since my videos are avi or ser I skip PIPP altogether. Both AutoStakkert and AstroSurface can handle frames from avi/ser files.

@tiny topaz ⬆️

[tiny topaz]

But if you hypothetically take 5 1min videos how do you get the 5 images together to stack all of the frames? Or do you stack all of them separately and then derotate?

[white prawn]

Stack separately and derotate

That arena is where I believe AutoStakkert might be preferred for stacking, even among AstroSurface fans, because AutoStakkert actually centers the planet

AstroSurface stacks based on where the video started.

[low tendon]

im thinking of going to sleep soon so will u process my jupi tmrw or like in a bit?

sry for being impatient lol

[white prawn]

I've been working this entire time ... will be later tonight. Not for the next couple of hours at least. If you sleep, you sleep and likely wake up with the processed Jupi.

Don't worry, I'm looking forward to working with it. 🙂

[low tendon]

ohhh u live in america, i live inn europe and here its 1am so night for u will prob be in like 5 hours, ima go sleep gn

[white prawn]

Ah, okay. Well gn.

[low tendon]

WOW

thank you so much

[torpid stone]

Saturn , Venus and Mars

Phone AP

[low tendon]

i think you could bump up the contrast aand the sharpening a lil bit, heres your process after i tweaked it a bit

[low tendon]

but bc i tweaked it with my phone its a lil compressed and also sharpening with my phone isnt as good as with a software so if u could do that i would appreceate so much

do you think 3minutes of video messed with my shhot cause of the rotation?

[low tendon]

i de rotated it and it looks a lil sharper now

[white prawn]

3 minutes didn't seem to be too long for my DSLR; however I'm pretty consistently doing 1.5 min now and I may at some point see how 1.5 looks on the DSLR if I get a night of good seeing.

[white prawn]

Believe it or not, I had a hard time with that because it didn't need a lot of adjustment. 😆 I'm soo used to working with seeing conditions that aren't ideal, or average, that I have to adjust wavelets a bit more than what I did here. So when I did the usual adjustments it was a LOT and I had to adjust

[low tendon]

thede rotation helped a lil

[low tendon]

my seeing was really goodd when i took it

[low tendon]

did u try processing it the exact same way as this??

[white prawn]

Haven't yet. Might not get to it for a few hrs. Lucky me works Saturdays 🙂

I did see what you did so I was going to try doing that. I think I can adjust contrast pretty easily on my end, I didn't delete the files I created as I was working with it so all I have to do is go in and touch up one of the edited and export to png again.

[low tendon]

thx again for all the proccessing

[white prawn]

I think this looks a bit better now.

This one seemed a little brighter and I was a little hesitant to apply too much contrast because I didn't want to lose shape or stuff but I went back to where I stopped before taking it into Gimp, applied more contrast, got it more on target.

[low tendon]

WOWOWOWOWO

[low tendon]

can u sharpen iit a tiny bit more?

[white prawn]

I tried to! 😆

[low tendon]

also last request, can i have the file so it isnt compressed?

[white prawn]

The tif that I was working with you mean?

[low tendon]

ye

[low tendon]

is this a screenshot?

[white prawn]

Nope! That's the png. If you click it, then click open in new tab, it'll load the png

You should be able to download

[low tendon]

yeah thanks!

insane process

[livid sierra]

Oversaturated and cooked imo, also bit too purple

Too much contrast

Easier on the eyes

[white prawn]

Fair.

I'll keep that in mind if I ever get a good night seeing on my images

[livid sierra]

@low tendon If you sharpen too much it gets too contrasty, and applying contrast on top of that makes it worse

@white prawn Did you use the curves in Astrosurface?

[white prawn]

This looks like what I had it at, when I first called it good.

[white prawn]

No, I actually took it out of Astrosurface after I finished wavelets and the initial gain/contrast adjustment. I finalize curves in Gimp

[livid sierra]

Yeah looked similar, still a tad too purple but sharpening looked more subtle

I see

I barely use any contrast adjustments on my image, just a tiny bit

[white prawn]

I'll try playing with curves in AstroSurface at another point/ another of my images. I'm starting to become more aware of its functionality.

So far the thing that I don't like is that when I pull an SER in for stacking, the planet can't be centered; it stays right where it was on the first frame.

As far as contrast - I think Tom gave me a hint about adjusting gain/contrast just a small amount to enhance curvature and get rid of flat disk and make it stand out from the background. And yahoo it works.

[livid sierra]

I was just wondering if that was what you used. I would stay away from the curves feature in AS tbh, it always does too much in my opinion

And also don't use Astrosurface for stacking, I tested the difference between AS!4 and Astrosurface a few days ago, and the Astrosurface stack was noticeably softer, less detail

[white prawn]

Okay, that saves me the trouble, thank you.

It did help me get a usable Mars image though.

[livid sierra]

Regardless, if you use the cutout box feature in Firecapture you wouldn't have to worry about the planet not being centred in every frame of the video

[white prawn]

I use SharpCap and it sounds like I'll have to do a quick learn of FC. If I can get my Nexstar setup maybe I can use that to remotely image planets instead of standing outside and adjusting the OTA.

I mean 4" vs 8" but the 4" is computerized.

[livid sierra]

Sharpcap is so far behind Firecapture in terms of planetary imaging, it's better for DSO. And sure, if you can find a way to control the Nexstar mount from your pc inside

The 8" will always perform better than the 4" though, tracked or not

[white prawn]

Yeah, I know that. She won't replace Rio, not by a long shot. I do want to see what can be done and get my hands on doing something remotely. Especially since I'm still in "below zero" season. Celestron 130 SLT for $80. For that, I figure:

• Familiarize myself with a form of computerized setup
• Familiarize myself with software that works better, especially w/ computerized setup (doesn't FC follow if you tell it to?)
• Ability to remote into the computer from a warm location when the weather is double-digit negatives
• Okay, let's see what 130mm can do (knowing full well that Rio is a more capable OTA)

I especially wouldn't mind the ability to control from inside since last time I went outside I had to spend some time at end of session defrosting my feet. After they were in wool socks and 40 below boots.

[main flume]

i dont think i ever will bc of strong air currents 😭

[low tendon]

i tried de-orbiting my jupi, put my coordinates, time in which the pics where shot and outlined my frame correctly , but itt just stackkedd it without de-orbiting, can someone help me out?

it just shmeered jupiter

[livid sierra]

Derotate after sharpening

[white prawn]

My understanding is that we do a little bit of sharpening, not a lot, before the derotate, then fully sharpen after the derotate. Basically sharpen enough for the program to see what's what.

[livid sierra]

I do it the other way around

Derotating is done to denoise by adding more data, so you sharpen beforehand, then derotate to reduce the noise

Possibly some very subtle additional sharpening afterwards

[livid sierra]

Idk where you get that from

[white prawn]

Was my understanding from Nick

[livid sierra]

Nick didn’t sharpen at all before derotating

[white prawn]

When I was talking to him about it he said to sharpen at least a little, enough so that the program could see the features, then fully sharpen after derotating.

If best results is to sharpen/process like its an individual image before sending it to derotate, I'll do that from now on when derotating.

[livid sierra]

Yeah best is to derotate after sharpening

The tif Nick shared earlier had limb artefacts which I suspect are caused by sharpening too little before deroating

[somber stratus]

The program doesn't "see" anything. It's purely map computation and stacking based on the outline frame you provide it.

Apparent contrast is irrelevant. What is needed is a sharp limb so that you can align the frame well.

[white prawn]

So basically process enough to get a sharp limb

[olive saddle]

Jupiter image taken with my phone and Orion StarBlast, I'm happy with it considering it's my first planetary image

[robust knoll]

Super cool!

[white prawn]

Niceley done

[rain hound]

Does anyone know why my stacked photo looks like this?, I used autostakkert and PIPP.

[woven tundra]

what the...

[south nest]

This has happened to me before, and using larger alignment boxes in autostakkert seems to fix the issue, I don’t know if that’s the best solution though

[white prawn]

You don’t need a lot of alignment squares. I use auto-place and a size that sets between 10-15 alignment points. Then I set a few points off the smallest size at areas of interest

[hasty hull]

I normally get like 80 APs on jupiter

But ig that’s just a 6M focal length moment

[left spindle]

I use 1 AP in jupiter (drawn manually ) and it works

[cloud copper]

Do you guys do noise reduction before or after derotating?

Damn

Using spacers between the Barlow and camera makes a huge difference

My newest image in kinda bad seeing conditions

Single stack

1000 frames

12” dob, imx224

Idk what the fl is now

And this is using the same rig but with less fl, seeing was abut the same

[left spindle]

That looks like deroation issue

[white prawn]

The one derotation I did so far: I did white balance and enough wavelets to define the edges, then ran it through derotation. Finalized wavelets and noise reduction after derotation.

[cloud copper]

It’s a single stack

I didn’t derotare

@dark cargo do you know how to calculate the fl after adding spacers to my Barlow?

Could be useful to see if I have good sampling

[left spindle]

Try

[dark cargo]

best option is to figure out the sampling via the planets size in the image, you can use this calculator. Just get the planets apparent diameter at the time from stellarium.
https://www.astropix.com/html/astrophotography/astrophotography-calculators.html#effosi

There is another calculator on here to figure out focal length from the spacing but you need to know your barlows focal length, which is usually not stated and I don't quite know how to figure it out.

Well I guess you could use the fl from the first calc then measure the distance from barlow to sensor and get it that way?

[errant rain]

Hey guys just wondering what this reddish dot on my Jupiter image is. I was recording Jupiter on January 30th, 8:20PM EST. I hope its a jupiter impact, but I need to verify with others if they were capturing if they also have it in their image as well. I tried two different stacking softwares and it appears in both of them. The seeing was abysmal, so bad that you cant even make it out in the live video. It only appears after stacking and sharpening using wavelets. I have done minimal processing because I dont want to introduce artifacts into the data. This has been sharpening in astrosurface using the wavelets function, and its been colour balanced. If you guys dont know if this is an impact or not where would I go to figure this out? ALSO, I completely forgot to point it out but Its the reddish dot on the lower equatorial belt on the Western side of the disc.

[cloud copper]

One or two?

[white prawn]

One. More contrast of colors, doesn't look ill.

[thin aspen]

One is a bit too blue for me

[livid sierra]

Maybe point out the spot you’re referring to? I see one little red spot and it just seems like a tiny disturbance in Jupiter’s atmosphere. An impact typically appears as a bright white flash, not red

[errant rain]

I made a post about it in the planetary gallery

[livid sierra]

An impact would also only appear for a very short time, say maybe a second or two

[errant rain]

its more detailed there

[livid sierra]

Yeah not an impact

At least I highly highly doubt it

Just seems like typical cloud disturbance that is all over Jupiter

[errant rain]

just a little more red then?

[livid sierra]

It is not even a weird amount of red tbh

[livid sierra]

I saw the post

[errant rain]

compared to its surroundings its noticable

[livid sierra]

The first image shows the scars left by Shoemaker Levy

Jupiter got bombarded with many fragments of an asteroid back then

[errant rain]

yes I am aware of what the other image is, I was just comparing them for the colour.

[livid sierra]

Well they don’t look similar imo and yeah again it doesn’t look like anything out of the ordinary

In your image

What you could do is look on alpo and see if anyone has imaged Jupiter when it showed the same face

And see if it’s there, but it won’t really make it any clearer if it’s an impact or not

Will just show that you captured the same cloud as someone else did lol

[thin aspen]

This is my image from last year feb and it seems to also have it.

[main flume]

blue

[craggy wasp]

is this good for a cellphone?

[main flume]

[craggy wasp]

the file didn't send lol

not compatible with discord 😭

[main flume]

[olive saddle]

Screenshot the image and re send it, that works for me

[wispy pagoda]

Hey! I've got thos UV, rgb and IR Venus but I have no idea how to process it cleanily. I can see the cloud but I need to sharpen a lot and it completely blows out the edge of the planet. If anyone is willing to give it a try or give advice, thanks

[whole osprey]

Hey, does anyone know of any good scopes (for planetary) that can go on the skywatcher gti mount? it has a payload capacity of 11lbs.

I doubt that any decent scopes exist that my mount can handle, I just wanted to see if anyone has any recomendations before I go into credit card debt by buying a new mount.

[dark cargo]

Usually they don't sell planetary dedicated scopes without a mount, but the 130pds(which should work fine for planets too) is around 9 pounds so would leave ~2 pounds for barlow + camera which might be just enough. The weight is according to FLO, might be able to find a more specific answer somewhere else: https://www.firstlightoptics.com/telescopes-in-stock/skywatcher-explorer-130p-ds-ota.html

Outside of that you could DIY a hadley aka a 114/900 OTA. Would be very cheap and much lighter, but you'd have a worse focuser than the 130pds one.

[whole osprey]

Ok, thank you so much!

[white prawn]

Your best OTA for planetary is really a Newt/Dob. I've also learned that if you're purchasing a Newt in a kit, most of the time you'll be getting a pretty decent OTA that's coupled with a mount that just barely meets the specs to hold what it's holding. Source: bought one. The good news is that those kits are usually inexpensive enough that you can always update the mount.

Unless, like me, you sold your house to get the setup and didn't realize until later that a better mount would have been more appropriate and funds are spoken for to the point that not a lot can be set aside for the mount.

[livid sierra]

You didn’t actually sell your house right

[cloud copper]

Do I need filters to capture clouds on Venus, is yes which one?

[white prawn]

Well ... there's a story.

Shortly after looking at things through an Amazon econo-scope (Gskyer 70mm) and realizing that I saw Mars one night and all it resolved as was a little red dot, I decided/knew I wanted something more suitable where I could actually see smaller stuff.

Shopped around, stumbled on telescope.com, found the Orion Skyview Pro 8 - 8" Newt on EQ5. About $700. An amount that was not in my back pocket. Wife and I were planning on selling the house soon anyway, so we had a discussion about use of proceeds, and agreed that I'd wait until the house was sold and use a few hundred to get the telescope.

Shortly after, as in "less than a year later" the house was sold and I used some of the money to get the telescope.

Given that I didn't have the funds at the time and it took the sale of the house to get them, I joke that I had to sell my house to buy it.

Now I'm seeing what is being done with a 16" dob and it's stuff that I'd like to be able to do. It wouldn't be practical to lug out the dob, though so I'd also need an observatory setup.

Time to sell the house again I think.

[olive saddle]

My first ever composition image, the Moon and Venus from last night. Two individual images, both shot with my iPhone 12 and Orion StarBlast dob using a stock 10mm eyepiece.

Stacked the best frames from a two minute video of Venus, and a 20 second video of the moon. Stitched together in post.

Unfortunately there were some trees in the way of the moon, but I couldn't possibly let this moment go to waste.

[woeful obsidian]

This is pic I took was taken on the 19th

This one has more black spots

[whole osprey]

What’s better for planetary?

Celestron c6
Or
Skywatcher skymax 150mm maksutov

[glad nexus]

both are so close in aperture (like within 3mm close). Maks are pretty much solely for planetary while SCTs can be hybrids. I'd do the C6 just for the flexibility

Worst case if you aren't zoomed in enough (i know everyone hates that term) you can buy a 2x or a 3x magnifier. 4x and above is on the edge of usability at 6 inches

and with the C6 being 200$ cheaper at the same aperture, I don't see a reason why

[whole osprey]

Ok thank you!

[lyric dome]

Anyone know how to find the software to track the ISS?

[summer pebble]

Decided to revisit some old data of Uranus and process it again (top)
Which one is done better?

[olive saddle]

I think the top one is more color accurate, and it appears to be slightly sharper than the previous process

not bad btw

[woeful obsidian]

Guys could this also be an asteroid impact

Looks more like an impact

[main flume]

we need tom

[woeful obsidian]

Yeah

[livid sierra]

No

[woeful obsidian]

Ok

[thick heron]

No

[unkempt igloo]

Top 👍

[sharp ridge]

Bro sees every darkish spot as an impact

[woeful obsidian]

I’m really new to planetary so idk shit

[shell epoch]

Well, that's insane for being really new

I only first looked at Uranus through my telescope a few months ago. After being in the hobby for over a year now

[left spindle]

literally been in hobby for 4 years and still i havent even found uranus 😭

[livid sierra]

Guys did I capture an impact perfectly centred above the GRS?

[somber stratus]

In fairness shoemaker-levy-9 impact scars were dark, but yeah. No

[summer pebble]

where even is the moon in this image

[summer pebble]

Mmm very cool awesome sensational double bright and dark impact indeed

[ruby tartan]

No

[teal sandal]

I want to capture venusian clouds with my mak 127/1500 + neptune 664c and i have some questions

should i use RAW8 or RAW16?
should i use only a W47 filter or W47 + Uv/Ir cut?
Should i use a 2x barlow or should i stay at 1500mm fl for this target

thanks

[livid sierra]

Raw8 is fine, use the w47 with a UV/IR Cut, but use one that passes at least at little bit into NUV (lower than 400nm), or you'll just be imaging in blue with low transmission

For the Barlow you should do some experimenting yourself, technically in UV the best sampling is with a higher f ratio but due to low transmission that is easier said than done and also your Barlow may have bad UV transmission

[teal sandal]

I already tried with the barlow but there were some artefacts due to thermal stabilisation so cant really tell

i think ill try without a barlow

im using an svbony uv ir cut

[main flume]

can sm1 process this for me pls :3

[livid sierra]

[craggy wasp]

jealous from the fact that I managed to get that result?

its really good tbh

[lyric dome]

1 moment bro

[lyric dome]

Yes

I’m making it better though

[craggy wasp]

that's good, I suck at procesing tho

[white prawn]

I can get it smoothed out. The colors on the other hand are borked ... and I do mean BORKED for me. It doesn't help that the color channels are completely identical.

[lyric dome]

lol.

[craggy wasp]

the struggles of not having a camera.

[left spindle]

shoukdnt be

[craggy wasp]

I'm saving for a good cheap one that can be bought here in Chile tho, I have bad experiences buying outside the country

[left spindle]

good

which one do u plan on buying

[white prawn]

Yes, well, there's "shouldn't" and then evidently there's me.

[lyric dome]

Ima finna make you happy

[left spindle]

lo

u got the grs

[lyric dome]

Actually idk if this is much better tbh

[left spindle]

i wish i had imaged at that time

[left spindle]

its good

[lyric dome]

This could be just me but im 95% sure there is a tiny sliver of solar eclipse left on the bottom right of jupiter @white prawn

[white prawn]

Moon eclipse, and yes definitely.

[lyric dome]

I mean it’s the same thing

It’s not a lunar eclipse

[white prawn]

I may have confused myself.

Anyhow, yes, there is a moon shadow on Jupiter, right on the edge.

[lyric dome]

idk whats better tbh

[white prawn]

I actually noticed that when I started working with the wavelets.

[lyric dome]

@craggy wasp posted a few

[lyric dome]

haha yeah, pretty cool

[craggy wasp]

hell yeah ty

[lyric dome]

this ones my fav tbh

[craggy wasp]

yeah in the original you can see the moon eclipse too

[deep island]

No. That´s @ruby tartan data

[white prawn]

This is as far as I got before the colors defeated me. But hey, I got the wavelets set.

[lyric dome]

what happened with your colors?

mine worked perfectly

[craggy wasp]

yeah you can see the eclipse there too

[white prawn]

I don't know. All the channels set themselves the same. #1019937457095065731 message

8" F5 Newt. (Rio)

[lyric dome]

ahhh nice

steve can you try my image?

[white prawn]

I bought that gear for getting into planetary AP before I really knew what I was doing. End result is that I bought a kit that consisted of an EQ5 and 8" telescope

[lyric dome]

to see how much detail you can get without grain

[lyric dome]

thats awesome

[white prawn]

Do you have the raw stack?

[lyric dome]

i do 1 min

ill have to stack it again rq

@white prawn 1st is raw, 2nd is raw sharpened in autostakkert

[white prawn]

There's ... a lot of blue in your image.

[lyric dome]

wdym?

thats almost deff from CA

[white prawn]

Yeah, that's a bright blue bit. Working on things.

[white prawn]

Realistically this one ... is likely over-done. I'm not pulling a lot of detail out when I don't overdo wavelets or sharpening. I know that seeing can do a number on what you can potentially get, and I know that if I asked my 72mm refractor to image Jupiter well, it wouldn't come out anything close to what I can get with my 8". (And I want to try with a 4", go figure)

I'm going to wrap up a little more ... just honestly I couldn't pull much. 🤷

[left spindle]

4"?

newt?

[lyric dome]

Its all good my man! I'm just open to everything

Do I need an ADC if I'm imagining mono?

And is CA on barlows that a big of deal in that case?

[fading plume]

Yes

[main flume]

did you ever finish it?

[thick heron]

I won't go as far to say ADC is required for mono but is highly desirable, especially with larger aperture telescopes. The easiest way to adjust them is with a cheap #47 violet filter which passes violet and near-IR light.

No ADC vs ADC with blue filter.

for 6 incher this is incredible good job!!!

[summer pebble]

seriously craving more aperture now...

[left spindle]

we imaged the same region on mars

man ive improved a lot

yup

wish i had a 6 inch haha good data

[summer pebble]

whoops

[left spindle]

are u barlowed?

nontheless your images look pretty great

[lyric dome]

That’s I saw

[lyric dome]

Thanks

[lyric dome]

Wdym

[olive saddle]

are you using a Barlow lens

[lyric dome]

No

I use a 3” refractor with a manual mount

@summer pebble idk how this is with ur data but

maybe too bright

wait

[summer pebble]

looking pretty good, but you can definitely sharpen that up more

[lyric dome]

sure but you don't want grain either

[summer pebble]

ehhh we all have our own philosophy for this

one man's trash is another man's treasure

[lyric dome]

indeed

@summer pebble

Hows this?

[summer pebble]

whoa!!!!

just compare it to mine

[lyric dome]

idk which is better

[summer pebble]

i am seeing some tiny artifacts here though...

[lyric dome]

That will happen when you sharpen too much

try this one

its less sharp

ill try ur mars now

[summer pebble]

edge rind is crazy fyi

one of the many reasons i crave higher aperture...

[lyric dome]

haha yes

ill show you mine with a 3 inch manuall refractor

thoughts? @left spindle

[left spindle]

Great but whats that bubble kind of stuff around mars?

[lyric dome]

edge rind

I have it too

[summer pebble]

i'll say your processing skills are likely better than mine!

[lyric dome]

really?

[summer pebble]

mhm mhm

the edge rind is less obvious in yours compared to mine

it alwaysss irritates me to see that

[lyric dome]

@summer pebble

thoughts?

[summer pebble]

hmmmmmmm

[lyric dome]

damnnn

is that the same data?

[summer pebble]

it is a bit awkward when the rings are on the planet

[lyric dome]

or differenct exposure just with moons

[summer pebble]

yep!

[lyric dome]

didnt even know they were there

[summer pebble]

(as far as my memory stretches it's terrible)

wait no i have this

gimme a min

[lyric dome]

ahhh

[summer pebble]

i was really surprised when i saw mimas was there

[lyric dome]

its very good

my saturn isnt good sadly

[summer pebble]

distinguishing the atmospheric detail is already good in my book

[fading plume]

Is the channel bleed on mono good enough it’s not needed as much?
Because in my head osc with adc and mono should be pretty similar.

[hasty hull]

This was my collection with my 6” dob, I have a 12” now and still haven’t been able to beat this Jupiter shot

Had some cracked seeing in ‘23

You’ve got some great shots there btw

[summer pebble]

Looking awesome

Seems like I have a tiny bit of improvement to go

[thick heron]

There is little channel bleed but still slight dispersion within the bandpass of individual filters.

[fading plume]

Ok so a osc image with channel alignment and a mono image without adc should be similar i guess?

Only difference being channel bleed?

[thick heron]

An OSC channel will be much more affected by dispersion. I've seen double images in blue channels with my old ASI462MC without an ADC since it was still quite sensitive as it crossed into near-IR from red. My ASI290MM images were subtly fuzzy but not unusable.

This was especially strong with Mars where you could still make out surface features visible in red light in both green and blue channels.

[main flume]

okii :3

[woven tundra]

this is incredible

[lyric dome]

thanks man

@summer pebble you got 3 moons

neptune

[terse night]

Oh wow, the difference in sharpness is very clear

[lyric dome]

hey ethan, with a 3.15" Refractor Manuel tracking, 900ml FL, and F/11 be able to see between saturns rings with a 2x barlow and perfect seeing??

[summer pebble]

Really?? Oh wow I didn’t realize I used a different exposure to get Them

[lyric dome]

very very faint

[summer pebble]

….where exactly are they again? I only see 1

[lyric dome]

top right, and bottom right

[summer pebble]

nah can't find them

match it with this and maybe i can find them

[lyric dome]

your edit is much better than mine haha

[summer pebble]

eh takes a bit of experimenting

[lyric dome]

whats your focal length?

[summer pebble]

3000mm after using a 2x barlow

[lyric dome]

damn thats why

thats neptune correct

My fl with a 2x is 1800

i can see a tiny slightly bigger than star dot

but i cant track haha

is yours manuel?

[summer pebble]

nah i use a celestron nexstar, so it can track

[lyric dome]

gotcha

Im getting an 8" tracking skywatcher

[summer pebble]

ahhhh sounds great

[lyric dome]

big upgrade from my 3" celestron 80AZ

😭

This mf

This is what I call, an inexperienced buy

Good heavens

Best i can get tbh

saturn could be better but thats from like 2 weeks ago

i got my telescope for christmas so

[woven tundra]

is this real?

[summer pebble]

Geez did a 3 inch refractor that is amazing

This was the best I could get for a cheap one

[lyric dome]

Yeah?

[lyric dome]

Dang haha

[thick heron]

As in through the Cassini Gap in the rings? Definitely not at this time with the rings so narrow. They need to be open wide to see it. In 2015 my 3.5" telescope and 1250mm FL could do it around most of the ring.

[main flume]

what u got :3

[lyric dome]

Damnnn I wish bro

[lyric dome]

@main flume

[lyric dome]

Got it

[main flume]

also you never did edit my planetary data

[lyric dome]

Ik bro sorry

I will

Keep getting busy

I edited it halfway last night and then distracted

[main flume]

xD

[cunning lily]

is this with a barlow? if so which one

[iron sparrow]

Awesome! Did you use an eq platform or did you do it the harder way?

[white prawn]

I'm wondering what you mean by "harder way". Alt-Az? Just tripod? No tripod, mount, hold the OTA himself?

[iron sparrow]

"harder way" as in just the dob mount without any tracking.

[white prawn]

TBH I don't know why I didn't consider that.

Though I was trying to be funny with the "hold OTA yourself while imaging" mental picture.

[hasty hull]

Thanks! These were with a totally manual dob, I have an equatorial platform now for my 12” dob

[umbral kestrel]

Venus

[main flume]

white circle D:

[olive saddle]

you got some glow from the uniluminated side too, awesome!

[livid sierra]

The nightside? That is not possible without a specific filter

Centred on 1010nm

Any glow you see on the nightside will be glare from the dayside and such

[olive saddle]

wait then why does it show up when you completely blow out the entire image

like you can see the rest of it

[livid sierra]

Not sure tbh but it won't be the nightside and also that larger circle around the planet raises some questions for me too

Not only the circle shaped noise on the nightside of the planet

[umbral kestrel]

Tf do you expect

It’s Venus

[umbral kestrel]

Just a artifact from possessing

[main flume]

mf i was joking 😭

[umbral kestrel]

Due to. Less then optimal colimation I had some rings. So I cut Venus out and pasted it in a different location in the img

And that large circle was just a clone stamp to remove the junk left behind

[livid sierra]

I suspected something like that yeah

In case you want to get rid of the noise you can decrease the offset by 1 or a few in Photoshop

[low tendon]

y does it stop analysing at 8%????????????????/

can anyone help?

[left spindle]

i used to have this prob, switched to astrosurface

[low tendon]

how do i use it

[left spindle]

one sec

ill send screenshots

select the region

after analysis click graph s

[low tendon]

field rotation ruinedd the stack

how can i fix it

[left spindle]

huh

are u alt az?

[low tendon]

ye

[left spindle]

i see then it will be a real pain to correct it

[low tendon]

bruh

[left spindle]

cut the video into shorter stuff

then stack it

[low tendon]

and then?

[left spindle]

nothing

i guess thats the best i can do

[low tendon]

wouldnt i just have lotss of pics?

[left spindle]

yeah but you would have lot of small stacked pics

rather than unstacked noisy pic

[low tendon]

bruh

isnt there any app that fixes it

[left spindle]

trying rotation rn

[left spindle]

tbh idk

[low tendon]

doest stacking also make a sharper image?/

[left spindle]

winjupos could.. but i dont know abt moon

[left spindle]

ye

try deepskyrotation

it worked for me

@low tendon

[low tendon]

ok

[low tendon]

im also untracked so it moves quite a bit

[left spindle]

same

still it would work

as it did in mine

[low tendon]

ok

[left spindle]

a lot of wierd artifacts

[livid sierra]

How long is your video that you have field rotation

Or was the moon at zenith

[low tendon]

wheres that?

[left spindle]

Analyse_register

then Multistars rotation

[low tendon]

cann u pls send a screenshot?

[low tendon]

thx

[left spindle]

np

[low tendon]

does your loading bar get stuck under the word align?

[left spindle]

Only once

[low tendon]

how long does iit get stuck there?

[left spindle]

Forever (i was too impatient so i canceled it)

[low tendon]

i thought u said it worked?

[left spindle]

Ar u talking abt astrosurface?

Ot worked with thaat

Was talking abt autostakkert

[low tendon]

bruh yhh

[left spindle]

Worked, if it dosent, check your frames by exporting your frames using pipp

Generally some naughty frame causes this

[low tendon]

that video im stacking is a bunch of videos joined with pipp

[left spindle]

I see

[low tendon]

there like 15 messed up ones

pippdidnt remove them

[left spindle]

Oh that couls be it

Oh

For the shacky frames while capturing i pause it and wait for it to stablise then i resume it (in sharpcap)

[low tendon]

no it a couple ones that are bugged

like half black

[left spindle]

That has to be the issue

[low tendon]

ok how do i deal with them

[left spindle]

Stack the seprate video files,(without rotation) and check which one causes error

Like gettinf stuck

Put those in pipp and export to tiff, remove the waste

[low tendon]

all of them i think, when im ttakingf the video annd the ccapture ends it buffers and the last frame is out of frame

[left spindle]

Oh

Then you will have to export to tiff and seprate the issue causiing frame

Or , choose quality estimator based on brightness of frames and then sprate the last frames after ezporting

[low tendon]

how do i change that, sry for all the questions im new to planetary

[left spindle]

I gtg sryyy ill come back in abt 30mins (mum calling for food)

[low tendon]

ok cya

[left spindle]

i m baaack

select these options

[low tendon]

where is options

[left spindle]

quality options, under that,( stuff like enable Quality estimator, Reorder frames, ans Total Brightness Algorithm

in pipp

[low tendon]

ohhhhh

[low tendon]

i caant open the combined vid

[left spindle]

hmmmm

wdym?

if data is small, i could handle half of it

[low tendon]

iit says error: avi codecot known by astrosurface, use pipp for conversion

[left spindle]

oh then convert using pipp

[low tendon]

i already used pipp to combine them

[left spindle]

put the input in pipp and simply hit start processing

[left spindle]

oh

wierd

[low tendon]

is there any way to manualy remove frames

??

[low tendon]

Can u help me?

[low tendon]

nvm i solved the problem

[low tendon]

NVM I DIDNT

I REMOVED BAD FRAMES BUT PROBLEM STILL HERE, IT GOT STUUCK ANNNALYZING AT 8%

AND I CANT CANCEL IT

SO I HAVE TO CLOSE THE WINDOW AND ALL THE WORK SEPERATING THE BAD FRAMES FROM THE GOOD WILL BE LOST

WTFFFFFFFFFFFFFF

SOMEONE HELP

[livid sierra]

Have you tried a clean install of Autostakkert

[low tendon]

i will tmrw but then ima have to sepparate all bad frames aagain

that took 1 hour

i stacked a 10 sec vid, (25% stack)

this process is terrible tho

heres the data if someone wants to play around with it (it needs rgb align cuz colours aare off)

[main flume]

or rgb misaligning

[livid sierra]

There’s PIPP and AS! itself that can do frame sorting by quality Idk why you’re doing it manually?

[main flume]

they like the pain of Manual labour

[left spindle]

ineed the actual not the conv one

[woeful obsidian]

Some frames are bugged and out of frame but still same sharpness so autostacker doesn’t reject them

And when I set pipp to grade them based on brightness the file could be opened by neither autostacker or Astrosurface and it just says that I need to convert them with pipp eventhough I used pipp to grade them

I’m so confused

[left spindle]

same thing happening with OP_Nick(ares c pro and dob ap)

can you give me a piece of the data, wanna try to solve it myself

[white prawn]

@livid sierra @low tendon @woeful obsidian @left spindle What do you make of this? Focus, collimation, or seeing? Or "yes" to the above? That's after some heavy wavelet effect.

I'm wondering if I should ask for the original data set somehow but it's a 35 GB video file.

[left spindle]

Could either be onion skining or a low number of frames stacked. The best solution us to dering it with wavesharp 2

Onion skining ia when the exposure of the frames you take is low but that ahoulsnt be a problem since u are uaing a planetary cam

[low tendon]

yes thats me bruh

just dif accounts

all op nick accs are minne

[low tendon]

just did, saame thing

[left spindle]

Lol

[low tendon]

stuck at8%

[white prawn]

That's someone else's data, not mine.

Also I've tried wavesharp, it's trash.

[left spindle]

Oh

[left spindle]

Why is wavesharp trash?

[livid sierra]

Try clean install of windows

[white prawn]

I've tried it, and it's more U... WTF rather than UI.

[left spindle]

Oh

[white prawn]

Couldn't get it to do anything

[livid sierra]

You sharpen

Drag wavelets slider to the right, increase sharpen amount

It’s that simple

[white prawn]

I can give it another go. I like AstroSurface though. 🤷

[livid sierra]

Yeah I don’t see any reason to switch to Wavesharp

[left spindle]

Dosent have deringing

[livid sierra]

Only reason I can see is the derind tool, but literally what it does is blend with the unsharpened stack I’m pretty sure. I can do that much and better myself in PS

[white prawn]

I think there may be times that I find it handy. Like I've moved most of my processing to AutoStakkert w/o bothering to use PIPP to extract frames because I'm imaging in ser mode anyway.

Just another tool, basically.

[white prawn]

Registax has that as well. I don't know how to do it in Gimp so it works out when I screw up the exposure on my lunar shots.

[livid sierra]

Honestly not sure what that means lol

[low tendon]

am i doing anything wrong? when i turn of stabilatation it doesnt get stuck which leads me to believe its those pesky frames but even when i removed them yesterday it still got stuck at 8%

[white prawn]

Install more RAM

[left spindle]

Truly wierd

[low tendon]

i dont have enough ram? i have 16gigs

[left spindle]

Have you tried other datasets with the same cam?

[low tendon]

yes only this moon data having issues

[white prawn]

When AS is running, just all by itself, how is the CPU and RAM usage? Also, what about the drive that it's on?

[left spindle]

[low tendon]

wdym the drive its on?

[left spindle]

Ssd or hdd

[low tendon]

???

[left spindle]

Autostakkert on the same drive as the data

[livid sierra]

Is your cam mono?

[white prawn]

What drive is the data on, is it solid state (SSD) or hard drive (HDD), and when it's processing the system may use the drive, how much is the drive being used

[left spindle]

SolidStateDrive or HardDiskDrive

[low tendon]

no
