Planetary Imaging

[coarse aspen]

prove it

[river hornet]

"so you like space name every NCG object"

thers more one sec

[frozen root]

[river hornet]

I probably should have put these in a thread

one sec

wait this is a thread

[coarse aspen]

yeah no you lost

[coarse aspen]

planetary needs likke 10 tb ssd lol

[coarse aspen]

WAIT WTF

how did you get an A drive

[river hornet]

this is all data

[river hornet]

[coarse aspen]

There was a 10tb HDD on sale for $80 the other day I saw

HDD*

[frozen root]

Take

Take and then convert to paged ram

[coarse aspen]

It was a great deal but forgot to buy

[river hornet]

w h e r e

[coarse aspen]

let me see if its still for sale

yeah sale ended, theres a 6tb for $90 though

i think it was cyber monday

[river hornet]

[coarse aspen]

dammnnnn

unlimited storage

[river hornet]

I've got more than that in my whole system already

[thick heron]

That is after compression with 7Zip

[river hornet]

turns out I am close but I did not beat

[coarse aspen]

Z drive?!

[river hornet]

you can name drives what ever you want in settings

heres everything

turns out I do hoard data

[river hornet]

[thick heron]

I think Windows starts with Z for network drives and goes backwards. I have another network drive labeled Y.

[coarse aspen]

I went ahead and deleted all the reg.tif files from DSS and it freed up a terabyte

Note: Clean up after DSS

[river hornet]

wait do you have the save intermedate files on💀

[coarse aspen]

I turned it off

And deleted all the ones where it was on

It was consuming all my storage

It freed so much to delete it

I'm gonna toss all my untracked data into 7zip since im not gonna be untracked for much longer.

[ruby tartan]

Do you save capture videos? I just save stacking

[thick heron]

I save all my videos.

[nova delta]

same, especially because my laptop has a 256gb ssd

[ruby tartan]

How many years of capture do you have there?

[thick heron]

Goes back to July 2013, so 9.5 years.

[ruby tartan]

😳

[thick heron]

Found my first Saturn recording from 2013-07-30. Taken with a 90mm Mak and ASI120MM unfiltered with 100ms exposures. At least it’s not saturated…

Back then, there were ASI cameras with different colors: gold for the ASI130MM, silver for the ASI034MC, and red for the ASI120MM/MC.

[onyx garnet]

Not bad

Here's my efforts

[frozen root]

why is it almost full @river hornet

also u spelt it wrong

asstrollogy

[river hornet]

Why ping

[coarse aspen]

Why ping

[river hornet]

It’s your drive not mine

[coarse aspen]

It was full because I saved the files from dss

the intermediate files

reg.tif

[frozen root]

i thought it ur drive

[frozen root]

why is it called asstrollogy ples at least spell it right

[coarse aspen]

its for asstrology

[frozen root]

asstrollogy

[coarse aspen]

its for asstrolLogy

[charred dagger]

Isnt that zodiacs

and astronomy the actual thing

[near quiver]

Yes

[topaz elk]

failed my finals because mercury was in prograde

[near quiver]

Dang that’s rough, odds were strongly stacked against you there

[topaz elk]

our school used to have astronomy class

not sure where it went

[limpid reef]

modern society almost has no more appreciation for anything astronomical anymore

schools teach the youth which aren't interested at all which might explain why

[thick heron]

I guess Saturn is now NSFW. 😅

[thick heron]

Or maybe not because I tried again and it accepted... ¯_(ツ)_/¯

[cursive inlet]

Saturn 🥵

[summer field]

Looks like Winjupos can deal with moon transits now

[somber stratus]

What WJ version is this

Latest I’m guessing

[thick heron]

Works okay, but may need work if near the limb. 1st is on & 2nd is off.

[sharp ridge]

🔥

[somber stratus]

Yeah bit too strong of an artefact for my liking on that first image

I suspect shadows might be better? Or just moons that are more central as you say

[fading plume]

@azure zealot why threads please

[river hornet]

you cant even make threads here💀

[fading plume]

real

[fading plume]

On the Perth AP group. 10k members

[somber stratus]

Never heard of Barry but top lad

I did make it very obvious on my posts that they were processed separately in fairness. Luckily it’s mostly gone through

Benefit of being transparent unlike certain imagers ig

[fading plume]

I mean technically it’s a composite but practically no. They are similar brightness etc. if you had no atmosphere and a much lower noise camera you would get this. It’s just composited for what it actually looks like. Not what we are limited by.

[somber stratus]

Yeah, Ik it’s completely valid as I captured the actual event - but at the heart of it - I did PS Mars in at the end of the day. Tbf almost all of the decent images were formed the same/similar way

But I just have to be transparent nowadays tbh. Much easier this way

[fading plume]

Yeah fair enough. The flerfs will still cry about it.

[somber stratus]

Certainly less so than they would have

[hasty hull]

Mars tonight

[summer field]

Yes, version 12.2.2

[strong leaf]

Would a ZWO ADC be necessary when imaging with an ASI224MC on a 10" dob? (254/1250)

[heavy mirage]

I wouldn't say necessary, but it does help get a bit sharper images

[strong leaf]

Alright, thanks!

[topaz elk]

i guess it depends on the altitude of planets that you get

if youre getting above like 50-60 degrees alt it can be negligible

[strong leaf]

Alright, good to know!

[cursive inlet]

Finally

[lunar hamlet]

Clear skies?

[cursive inlet]

Havent had proper clear night for months now

[lunar hamlet]

Well use it well

[cursive inlet]

Yeah gonna try to get a last shot at mars since its still pretty big

[limpid reef]

are you two the same @cursive inlet @limpid topaz

[cursive inlet]

Lol

Yeah he’s my evil twin brother

[near quiver]

True… but what does this have to do with planetary imaging???

[limpid reef]

guga is a planetary imager

[cursive inlet]

How the hell do you find uranus without go-to

Ive been starhopping for like half an hour

[heavy mirage]

Some Saturn data in share my data from November 17
https://discordapp.com/channels/794642864218439681/1052660249808617582

[limpid reef]

finder scope maybe ?

[cursive inlet]

Already captured some data but damn from a city its so hard to find

[limpid reef]

:(

[topaz elk]

still can't believe i shot this with a dslr using manual mode

around 300 individual photos i think

[hasty hull]

I try to roughly triangulate it’s position with 2 stars, and then look around until I find something that looks like it could be it

And then slap the Barlow on to see if I can resolve it into a disc

I can normally locate it within like 5 minutes that way

[cursive inlet]

Hmm maybe ill try that next time, thx

[alpine willow]

Surprisingly sharp for a dslr

[topaz elk]

mirrorless but around same thing

[hasty hull]

You could try something like this

Meeting at this point and then moving to the top left

[cursive inlet]

quick process of mars 3 hours ago, looks very promising

Is that cloud on the bottom left or is it just some kind of artefact?

Gonna try to process my uranus data, did a 685nm pass run along with color, idk if its gonna be anything good

[wispy pagoda]

Processed some of Ken's old data

[main flume]

Can someone proses this

[onyx garnet]

It's.. not very good data

[main flume]

I know

I took it with my phone

[onyx garnet]

Here's mine with my c6 and phone

[main flume]

Is good

[onyx garnet]

Indeed. What are you using?

[main flume]

Celestron 114az-sr

@onyx garnet hello?

[onyx garnet]

it's 8.30am i'm tired

[onyx garnet]

k

[main flume]

7:38 my time

[onyx garnet]

k

[lunar hamlet]

Here’s mine

[onyx garnet]

Nice

[near quiver]

Had a lot of cloudy skies recently, here’s a slightly reprocessed Saturn. iPhone X, 8” dob

[onyx garnet]

Could I try to edit the picture itself?

[near quiver]

I would but I’m not home right now so I don’t have access to the raw image

[onyx garnet]

Nono the picture you sent is fine

I'll edit that

[ebon sage]

Not gonna work very well

[near quiver]

Oh ok go ahead

It’s not going to be great but feel free to try

[onyx garnet]

But i'm happy to use the raw inage too

[near quiver]

Very nice

[onyx garnet]

Thank

[sharp ridge]

[sharp ridge]

its a cloud

[cursive inlet]

Awesome

[alpine willow]

Frosty

[heavy mirage]

Yes, but totally worth it

[cursive inlet]

Whats your aperture?

[heavy mirage]

10 inch F/4.7

[onyx garnet]

that's really nice

I like it

[heavy mirage]

Thanks!

[somber stratus]

how cold

[cursive inlet]

managed to get a little pole brightening on Uranus, 685nm pass

[heavy mirage]

-2, -3. not super cold just a bit humid

[somber stratus]

yeah painful

[topaz elk]

bruh how does that work

[topaz elk]

😢

[ruby tartan]

😨

[topaz elk]

quick process of around 3 minutes

[hasty hull]

Woah great

That’s with the 8” dob?

[topaz elk]

yes

[hasty hull]

Good stuff

[topaz elk]

thanks 👍🏻

[somber stratus]

moon spotting

diffraction spikes are the triangular regions at top & bottom

ik green lol

cba to change it atm

[wispy pagoda]

Wow

Beautiful

[cursive inlet]

🤯

[near quiver]

Woah, can’t wait to see the final results

[coarse aspen]

That looks like so high resolution

[somber stratus]

16" resolving power

[coarse aspen]

are you doing the whole planet?

like rotation

[ruby tartan]

@thick heron Congratulations

image of the day in astrobin

[somber stratus]

idk, i've got about 2/3 of it so far

dont really plan to get the whole thing but i could

[coarse aspen]

would look nice

[thick heron]

Surprised the original processing got farther, but honored nonetheless!

[heavy mirage]

Jupiter right now

[ruby tartan]

👌

Mars right now

It's been like this for 21 days

[coarse aspen]

Damn that's some insane seeing you can see dust on Mars

[wispy pagoda]

Pretty much the same thing for me
For more than 4 months now, there are clouds, clouds and clouds. Or clear skies but Im at the wrong place so I can't image

I had around 4 astro nights in 4 months

And 3 of them were very short because of wind, dew and clouds

[somber stratus]

Nice cloud structure. Be sure to submit it to ALPO or similar

[somber stratus]

my clearest phobos detection yet

[heavy mirage]

Saturn today just after sunset at 25 degrees alt, so far just stacked one vid

[ruby tartan]

Finally, after 21 days without clear skies, there was a break, I only got 10 minutes of videos *(goal was 30 minutes), very bad transparency but seeing good

[ruby tartan]

Jupiter tonight

[nocturne zinc]

Whoa, what telescope and camera?

[nova delta]

Same telescope - Skywatcher Heritage 150P GTi, same camera - ZWO ASI 120 MC-S, different focal lengths
Top image was taken at 750mm
Bottom image was taken at 2250mm

[nocturne zinc]

Is that a moon on the left?

[nova delta]

yes 👍

[lunar hamlet]

[near quiver]

This will be fun to image, just a few months after total solar eclipse too

Also just fun to look at

[lunar hamlet]

Good luck with it

[near quiver]

At least I have time to prepare

[lunar hamlet]

Yeah

[topaz elk]

@near quiver what about jupiter occultation nezt year?

[ruby tartan]

Gso 8" + qhy462c

[near quiver]

Oh really? I didn’t even see that

When is it

[topaz elk]

april19

[near quiver]

That will be fun, I hope I don’t miss it like the mars occultation 🤞

[wispy pagoda]

Too low to be interested I believe

[topaz elk]

it depends on where you live

however it happens during the day

[near quiver]

Oh right I did see that but it looked real close to the sun

[hasty hull]

Yeah that’s only a few degrees elongation

Very unlikely anyone will get it, but we will see

[near quiver]

Maybe someone will be very brave

[thick heron]

We get another Jupiter occultation in May, just as the Sun rises for me.

[wispy pagoda]

Yes it's what I meant

[heavy mirage]

Crazy seeing the other night, this is a single frame at 25ms 120 gain

[near quiver]

Holy cow

[heavy mirage]

Mars was at nearly 70 degrees alt too

[near quiver]

That’s going to be a fantastic final image

[heavy mirage]

forgot to rgb align,

[topaz elk]

dang

one frame

good seeing but 0 c

[fading plume]

shite

shame its sooo hot the heatwaves coming off everything are killer

[swift marten]

Meanwhile it’s going to be -10 C the next clear night here

[fading plume]

stars are twinkling at zenith. x to doubt

[frozen root]

[ebon sage]

when metroblue says seeing is super bad its always good

and vise versa

[obtuse yew]

Damn and there's a shadow trasit at the same time

[somber stratus]

US only i think?

close pass for Europe, during daytime hours

We get a nice Venus one on Nov 9th 2023 if i remember correctly

[ruby tartan]

https://eco.mtk.nao.ac.jp/cgi-bin/koyomi/occulx_p_en.cgi

This site has all the occultations that will happen until 2035

[thick heron]

There is a program that does all sorts of occultation predictions and is great if you can figure out how to use it: http://www.lunar-occultations.com/iota/occult4.htm

[frozen root]

I’m not missing this one

[alpine willow]

What, with your redcat?

[frozen root]

have a 6" dob

+183

[alpine willow]

Nice

[frozen root]

should be good

[alpine willow]

183 isn’t what I’d want but sure

[frozen root]

dont have another color cam

I can get it in mono

ig

with my guide 120

[topaz elk]

http://www.lunar-occultations.com/iota/planets/planets.htm#:~:text=Saturn and Neptune are not,remote areas or daytime events.

happens during daylight tho

no atmosphere, but you can get a double shadow based on where you live

[nova delta]

that would be sick

[coarse aspen]

I'll miss it

I'm in occultation zone but too close to the sun im not comfortable with that

[topaz elk]

do yall get streaks around jupiter when you look at it with naked eyes

[hasty hull]

Kinda sorta

[alpine willow]

Nah just crop your 183

Also get a damn uvir cut filter

This is why you have big stars and low sharpness

[frozen root]

Fine

[ebon sage]

bruh i miss this one aswell

[coarse aspen]

yes

[topaz elk]

isnt that astigmatism or am i tripping

[coarse aspen]

astigmatism

i got it too

[topaz elk]

damn i need glasses

[hasty hull]

My astigmatism is even worse with glasses

[fading plume]

like diffraction spikes?

[topaz elk]

nah, like a thin halo around it

[fading plume]

dirty eyepieces or something i guess

[topaz elk]

no with naked eye

no eyepiece

no telescope

[fading plume]

rip eyes

[near quiver]

i get that with the moon

[topaz elk]

wearing glasses = better focus

[ruby tartan]

Mars tonight

Average seeing, terrible transparency and low planet on the horizon

[topaz elk]

whats up with that giant cloud on the bottom left

seen it on almost every mars pic despite the face of the planet

[ruby tartan]

I can't say, it's been 1 month since I captured mars, but it was already showing up

[cursive inlet]

Lol my image from a week ago has that too

[topaz elk]

same for mine

but how come its never in the middle of the image

🤔

always bottom left

[near quiver]

ok well now this is a mystery

i guess its silly to say that its a cloud moving at exactly the right speed

[cursive inlet]

Tom’s image from the 16th

[cursive inlet]

Geostationary cloud 🤔

[hasty hull]

It’d be the opposite right

[cursive inlet]

Oh yeah ur right

Anti geostationary cloud

[frozen root]

Feel bad for that one region that gets it

[cursive inlet]

Pretty sure I’m in that region

[cursive inlet]

Nah but its not the region, the cloud stays in place from our perspective while Mars spins.

[frozen root]

F

[cursive inlet]

Do clouds just do that? It looks so weird.

[frozen root]

Your always going to get that cloud

[frozen root]

Not that I know of

[near quiver]

can it be seen on older images?

[frozen root]

Yeah

[near quiver]

i wonder if the light is diffusing in the atmosphere to do that?

[frozen root]

Check probes orbiting mars

[cursive inlet]

It came into view towards the end of November it seems

[somber stratus]

morning clouds

they form during the local night, then rotate into view, only to dissipate. it's not a permanent "feature" per se, the only reason it's started to happen these last few months is due to the melting of the northern polar cap. The atmosphere has a lot more vapour available to form clouds atm, with activity expected to increase further.

much similar to fog/mist here on Earth; forms overnight, then dissipates

[near quiver]

Ah, in comes someone who knows what they’re talking about right before I was about to say “aliens”

[topaz elk]

wow

[thick heron]

We should see more of those blueish clouds as Mars approaches aphelion and the atmosphere cools off from less solar energy.

[hasty hull]

Mars tonight, very very good seeing

Definitely overcooked, better process will come tomorrow

the stack if anyone wants to have a go

[somber stratus]

Why I’m looking forward to the next few oppositions, despite the poor size

Tharsis region especially

[coarse aspen]

Scnr

[cursive inlet]

?

[coarse aspen]

its green

[cursive inlet]

I have night light mode on my monitor maybe thats why

Hold on

[coarse aspen]

I mean its not completely green, but theres definitely a green tint to it

[cursive inlet]

Willaf’s original data was very green

[cursive inlet]

Idk i dont see it lol

Maybe im colorblind

[hasty hull]

Nice great job, this is my 2nd attempt

[cursive inlet]

I think your image got compressed a bit

[heavy mirage]

Not sure if I like these colors but here's my attempt

[hasty hull]

Wow amazing, what’d you use?

[ruby tartan]

My attempt

[heavy mirage]

Mostly AstroSurface for wavelets/denoise/white balance and GIMP for final touches

[obtuse yew]

The next oppositions will occur closer to aphelion? And for that reason form more interesting clouds?

[somber stratus]

yes

[obtuse yew]

That's a nice silver lining. The next couple oppositions really are pretty lame in terms of size

[hasty hull]

What’d you use to control the ringing?

[heavy mirage]

Lighter sharpening, and when using ps/gimp you can also use select by color tool, select the background and grow selection by 2-3 pixels. Then feather 10-20px to make edge less sharp and use median blur to make the ringing less prominent.

[main flume]

Hello

[wispy pagoda]

Hi!

[lunar hamlet]

This is planetary imaging?:v

[quick umbra]

What rig did you use for Jupiter and Saturn?

[quick umbra]

Oh I quite like it

you can see one of the moons and shadow

[normal forge]

Is collimation spot on? How was seeing and transparency at that night?

[quick umbra]

The image is a tad noisy

[weary jungle]

@normal forge

[normal forge]

this color correction looks pretty solid! 🙂

you did not use an ADC right?

i like the image. not sure what win jupos maybe could do with derotating and stuff. 🙂

[weary jungle]

Thanks and no I did not use an ADC I might invest in one in the future. I believe it was decently high in the sky as well so I didn’t really need one at this point.

[somber stratus]

when did you take this?

[weary jungle]

Oh my gosh I just realized this is the wrong data that’s my bad I’ll take this stuff down

[ruby tartan]

It looked like an old photo to me because of the bands and colors of the planet and the placement of the shadow too

[somber stratus]

lol

yeah

it's from the opposite season

Jupiter season that is

6 years ago

i suspect this isnt even your data

[nova delta]

the image looked like the fire capture dummy cam lol

[weary jungle]

Yeah oh shoot I got confused with my other data because it’s under the same names that’s my bad

I promise I wasn’t trying to lie I really thought it was mine sorry

[somber stratus]

when was it from

date

curious

[weary jungle]

I don't even know I only have the date of when I downloaded it. but I would imagine pretty old now that I look at it

[ruby tartan]

I think the date is between 2013 and 2006

[somber stratus]

could be this

Ganymede is transiting the NPR, not southern

It's 2019 or 2006

ish

[nova delta]

very similar i guess

[somber stratus]

how do you mistake firecapture dummy cam as your own data

[nova delta]

i'm just saying it look similar 🤷‍♂️

[somber stratus]

it's identical

Festoons match

bruh moment

[nova delta]

[coarse aspen]

No

I took that

With my phone and 3x barlow

[strong leaf]

First time capturing mars and jupiter with an asi224mc, tried processing but only getting 2 allingpoints which messes the alligning up. Not even sure if the data is processable since I was very unlucky with the clouds

https://easyupload.io/m/ydorzz

Here are the .SER files if anyone wants to have a go or just give feedback on the data of what I can improve on

Taken with a 10" dob untracked

[weary jungle]

Because I use fire capture to capture and they are under the same names with just being random numbers.

[wispy pagoda]

Insane seeing rn, it's the best live view that I've ever seen in mars and yet it's trough naked eye visible clouds!

[wispy pagoda]

Really quick process

[alpine willow]

Good stuff

[cursive inlet]

Bruh its a christmas miracle i have 4/5 seeing rn

Io and europa are disks in live view

[alpine willow]

Resolveable detail?

[cursive inlet]

Nah but they looked like proper disks in firecapture, and jupiter had a bunch of detail

[alpine willow]

Very nice

Please send result

I Wanna see

[cursive inlet]

Yeah im warming my hands rn

Gonna try to get uranus

Prob gonna be my best jupiter and mars for the year

[wispy pagoda]

5/5 for me!

And first clear night in like 2 months

[lunar hamlet]

Quite bad, if anyone wanna process it, I can send the file

[cursive inlet]

Pretty frosty lol

[hasty hull]

[summer field]

Not as bad as it looked like with the naked eye

[silent star]

Freakin hate this, I mean this is my first attempt

[fading plume]

sharpened?

[lunar hamlet]

Idk, it’s bad though

[fading plume]

It looks similar to my badish unsharpened pics

Did you sharpen it at all? Because that’s a very important step. Use registax

[manic pecan]

Can u rate my jupiter 1-5

Yea 1st stack

[silent star]

For a first time stack, it's actually pretty good! 4/5

[hasty hull]

Solid work

Keep it up

[lunar hamlet]

I did but I suck at it

[cursive inlet]

what do yall think of this framing? Tried something a bit more creative

[hasty hull]

Sick shot

Love it

Framing is cool, but if you can I’d leave a bit of room on the sides

[weary jungle]

I like it also I noticed your using a ASI 462MC I have one but have had some problems getting clear shots with it how has your experience been?

[cursive inlet]

I've been liking it a lot, very good camera and little to no problems. What kind of issues have you been having?

[weary jungle]

I think it could just be a low quality Barlow or my optics were out of collimation but it just seemed like it wasn’t ever clear and when edited it was just a big fuzzy ball and I was adjusting focus to the best of my ability so I am not sure. Also seeing could have just been really bad that night. Are you using a UV/IR cut filter?

@cursive inlet

[cursive inlet]

Yeah the UV/IR cut is essential and the absence of it hinders the clarity and color balance a bit, but I think in your case it might be the seeing, I've had some really shitty nights lately where it looked like Mars was nothing more than a soupy blob.

[weary jungle]

Alright yeah I have one and haven’t noticed a huge difference in clarity but I will use one for now on I appreciate the help and will get back after I do some more shooting. Living in Ohio I don’t have a lot of clear nights so that’s unfortunate

[cursive inlet]

Cool, I recommend getting yourself an infrared pass filter. The 462 is like one of the best ZWO cams for infrared planetary. Infrared light waves are larger than visible light so they are less disturbed by the atmosphere. It has really made some of the worst nights worth it.

I have a Mars capture from 3 weeks ago, seeing was like 1/5, but the ir pass still got me a decent-ish image.

and then you just combine them:

[weary jungle]

Alright thanks do you recommend any certain one like a certain brand?

[cursive inlet]

what scope do you have?

[alpine willow]

Insanely good for 1/5 seeing

Which IR pass are you using?

[weary jungle]

I will mostly be using a C14 or a 10” Meade SCT but mostly the C14 I also have access to a 18” obsession Dobsonian. They are my local astronomy clubs telescope

[cursive inlet]

685nm pass

[alpine willow]

Which specifically tho

[cursive inlet]

Antlia

[alpine willow]

I want to get an IR pass for my 585

[ruby tartan]

IR pass always saves a capture of a bad seeing

[alpine willow]

Is there much benefit for using the 850nm+ band pass filters? Or is it worse

Those are usually cheaper so

[ruby tartan]

If your telescope has a large aperture it compensates, the longer the IR the less resolution the image will have

[cursive inlet]

Those are nice scopes, search for any ir pass from 642nm to about 850nm, the brand doesn't matter I just got the cheapest one I saw.

[alpine willow]

I’m aware of that, I’m speaking from the perspective of whether the seeing at 850+ is better than 685

And if the sacrifice in QE is worth it

[cursive inlet]

I have a comparison image from a few weeks ago hold on ill find it

[alpine willow]

At 850nm I’m looking at a QE of like 55%m 685 is more like 85%

[alpine willow]

Interesting

[ruby tartan]

I have this comparison

[alpine willow]

Venus is a bit of an exception though because of the different gasses in its atmosphere

[cursive inlet]

Basically they are only good on Venus

[alpine willow]

Aight

685nm it is

[cursive inlet]

yeah its also nice for uranus

since you need the extra light for that

[alpine willow]

I can’t really even resolve Uranus well anyway so

[ruby tartan]

Uranus with IR685

[alpine willow]

Fl?

[ruby tartan]

I have this mars comparison too, seeing was average

[alpine willow]

@ruby tartan konus eq5 user???

I thought I’d never see the day

[ruby tartan]

focal length? 4000mm

[ruby tartan]

Yes

[alpine willow]

My mount for it is long gone but I still have the OTA

[ruby tartan]

My setup is falling apart, her tripod is tied with a string

[alpine willow]

I had the exact same thing lol

https://media.discordapp.net/attachments/794651916646350859/913159728392175646/DA682A5F-B6DA-42A2-AC97-9DF123C994B9.jpg

[ruby tartan]

EQ3?

[alpine willow]

Ignore the missing counterweights

It’s the eq4 technically I think

[ruby tartan]

I want to buy an EQ mount from a manufacturer here in Brazil, it has a payload of 32kg and costs less than an eq6

[alpine willow]

Which?

[ruby tartan]

An eq6 is costing 16 minimum wages here 😨

[alpine willow]

[ruby tartan]

Dony mount

Some eq he is making

[alpine willow]

Nice

[somber stratus]

ASI462MM ordered
Present to myself.

For Mercury, Venus, Uranus, Neptune & Lunar imaging.

Potentially ISS too but unlikely

P1 Uranus-C still reigns supreme for Jupiter, Saturn, Mars & colour ISS

[ruby tartan]

Nice

I'm going to buy one next year

[weary jungle]

Wait there’s a monochrome version of the 462MC?

[somber stratus]

yeah, about a month now

[weary jungle]

Oh cool I have the colored I would want to see how they compare.

[thick heron]

The camera I had been waiting 2 years for but my heart was stolen by the QHY5III200M at the last second.

[cursive inlet]

Unrelated but whats the story behind your profile picture?

[somber stratus]

What won you over in the end?

camera characteristic i mean

[warm bay]

@somber stratus i am having a pretty hard time finding focus with a 2x barlow and m planatary cam

is there an easier way of finding it?

whilst being able to slew to jupiter

[somber stratus]

Not really. You can use the camera with overexposed settings. Sometimes shows the glow of Jup when it’s nearby

For focusing just run it in & out until you find the spot

To the focuser extremes if needed

[thick heron]

I accidentally set a wavelet in RegiStax to a negative strength. The image is from March 1, 2014 with an Orion 90mm Mak and ZWO ASI120MM.

[cursive inlet]

Cool

[thick heron]

Can't directly compare with the mono 462, but I do have the color version and the noise of my 200 is lower, especially the fixed pattern noise.

I am also hoping it works well with Venus night-side imaging since it is a case where old CCD cameras have performed better than CMOS. The problem with most of the newer CMOS cameras is that they have significant diffraction artifacts from the day-side that overwhelm the night-side. The only exception I know of is the IMX174, but it is less sensitive to 1 micron infrared than the old CCD cameras.

[somber stratus]

i see

[strong leaf]

Is it possible to stack multiple captures together in Autostakkert? Took 7 30s captures of mars, but can't seem to stack them all together, it just does them one by one

Or do I need to use a different program?

[thick heron]

You can open the videos in PIPP and change it to “Join mode”. I don’t think AutoStakkert can combine videos.

[strong leaf]

Ah okay! That's really helpful! Thanks

[barren dune]

Havent been here in a while hers my occultation shot

[sharp ridge]

edges are too blue

[cursive inlet]

What fps do yall do Uranus at?

[ruby tartan]

In visible light I capture at 20fps

In IR685 I capture at 10fps

[cursive inlet]

@ruby tartan do you collimate with laser or cheshire?

[ruby tartan]

I collimate the primary with a laser and the secondary with my camera and an allsky lens

[cursive inlet]

Interesting, you mean the lens that comes with the zwo cams, can you elaborate on your process?

[ruby tartan]

Yeah, those same ones, but in my case a qhy

[ruby tartan]

https://www.youtube.com/watch?v=00zSzDr8SXA

I think the cheshire does the same thing, but with the camera it's much easier

[somber stratus]

Yeah I just use a Cheshire and collimation cap

Does the job

[somber stratus]

~35fps with both RG610 (IR) and UV/IR cut (visible)

2.9um cam at f/21

Integrate about 30mins minimum

[cursive inlet]

can you share some pics?

[somber stratus]

On phone but I’ll see if I have any saved on here

Single stack OSC, with UV/IR cut (visible)

[cursive inlet]

damn thats why I had such a hard time last time I did uranus, I was trying a similar aproach as I do Jupiter or Mars, my fps was way to high and I was compensating with gain.

[somber stratus]

IR(RGB). About 30mins of IR, 5 mins of colour data

Moons from mid of capture

[somber stratus]

It’s not too bad, depends on f ratio

You do get sharper results from shorter exposures as per lucky imaging

[cursive inlet]

I do it at f/18 but my aperture is only 8 inches, still got polar detail but I will try less fps next time

[somber stratus]

What filter you using

[cursive inlet]

mind blowing

[cursive inlet]

685nm pass for IR

Idk why I thought shooting at 100 fps was a good idea

[somber stratus]

Yeah so the image will be darker than it is for me with the RG610. You might find you need about 40-45mins

I would use 30ms exposures or so.

30-35fps

[cursive inlet]

thanks for the tips

@somber stratus wait what about just using a visual red filter for the pole?

[obtuse yew]

Thanks for that information about aligning the secondary Lucca

Very helpful. I've always had trouble with the secondary

[ruby tartan]

Same thing here

[ruby tartan]

same thing here²

[ruby tartan]

We have the same telescope aperture, try to use 50ms for visible light and 100ms for IR

[cursive inlet]

will do

[ruby tartan]

https://www.astrobin.com/i81y3z/?nc=&nce=

This image was taken at f/20

[somber stratus]

Depends which one

[ruby tartan]

I captured this image at 50ms, 6000 stacked frames out of 25000 captured

[somber stratus]

You’re not really lucky imaging at this point. Tracking inaccuracies come into it too

It’s fine for excellent seeing but that’s not the case 90% of the time

[cursive inlet]

just noticed we also use the same sensor

[somber stratus]

100ms is way too long imho. Maybe for near perfect seeing but idk

Sceptical about this one

[cursive inlet]

hmm, I used 100ms for some dso lucky imaging, I think its too much for uranus

[somber stratus]

yeah DSOs are much dimmer than Uranus

[ruby tartan]

I agree, I use 100ms when the seeing is very good and the montage is perfectly aligned with the pole, in my image above it was taken at 50ms, avarage seeing

[somber stratus]

You don’t need to use such long exposures

That’s my point.

[cursive inlet]

also the 462 is like really good for IR

[somber stratus]

Integrate a little more if you have to, but I’d still stay below 40ms imho, personally I don’t like to venture far beyond 25

For typical seeing*

[ruby tartan]

Yes, one of the reasons I chose this sensor

[somber stratus]

Why I just got the 462MM

No bayer matrix in the way this time

[cursive inlet]

I have an 850nm pass and apparently you don't need to debayer with the color version of that cam with that filter, whats ur opinion on that? I tried it and it appears to work, basically like a mono cam.

[ruby tartan]

I'm going on a trip today, when I get back I'm going to buy the mono version and a filter kit

My camera also came with an IR850, but I think it's too long for an 8" aperture, so I ended up selling it to buy another filter.

[somber stratus]

Yeah true.

[ruby tartan]

It basically rules out seeing and atmospheric dispersion, great for Venus and Mercury.

[cursive inlet]

yeah but I think it would be good lunar? The moon is pretty bright 😅

[somber stratus]

You have to debayer regardless. It’ll be near B&W though when using default colour balance settings. I just debayer then desaturate -100 so it’s in B&W

[ruby tartan]

I have some images with him, I think I even sent some images of Venus that I made with him

[ruby tartan]

I think it would look good with Tom's telescope, ours would be too heavy for our aperture

[somber stratus]

Yeah I have a 850. Still rarely does better than a 610 as per diffraction limit

Even with my seeing and aperture

[cursive inlet]

Fr? The zwo website says you can do without debayering, and in FS when I turn off the live debayering it just looks b&w and you cant see any of the bayering grid you would normally see in color.

[somber stratus]

I’m going to attempt Uranus’ rings with the 462MM & IR850 at f/8.8. Should require about 2hours integration by my calculations, comparing to the setup used by Martin Lewis when he got the rings

[somber stratus]

Yeah, you’ll get that horrid pattern otherwise

[ruby tartan]

Good luck

[cursive inlet]

I mean like when I turn off the debayering, when shooting in color I see a pattern, but with the 850nm and the white balance at 50 I see nothing, so no debayering needed then for 850nm?

[somber stratus]

Uranus is 10x dimmer with the IR850 vs the 685 as per the CH4 absorption band. I did a few tests at f/21 with the Uranus-C and the major moons were visible whilst the planet was still normally exposed.

[somber stratus]

It’s still there I’m fairly sure

Just not as noticeable

[cursive inlet]

I thought it was like transparent in the longer IR wavelengths, some people said so.

[somber stratus]

Mostly, but I always like to debayer then convert to B&W regardless

doesn’t change the result

[cursive inlet]

I thought the bayer matrix still causes some loss of detail?

[somber stratus]

Linear image. Not stretched. 2 hours IR850 with Uranus-C at f/21. F ratio is way too high and the camera sub-optimal for ring detection.

[somber stratus]

Don’t think so. Not in post processing. The damage is done when the light first enters the device

[somber stratus]

The existence of the bayer matrix in colour cams in the first place makes the difference

[cursive inlet]

Yeah so if the 850nm light passes right through the matrix, no damage?

[somber stratus]

It’s not exactly monochrome there though. Also there are still 2x G, 1x R, 1x B pixels

[cursive inlet]

Probably only useful for wide moon shots bcs defraction limit.

[cursive inlet]

negligible? or no?

[somber stratus]

It’s small yeah, but still has an effect

I’ll do some tests when the Mono version arrives. I have both the MC and MM then

[cursive inlet]

@somber stratus Whats ur experience with venus in IR? When browsing images I see people use different ir filters all the time.

[somber stratus]

Depends on seeing. 850 if it’s trash, 610 otherwise. 685 also works but I don’t have one

Deeper IR has more chance of cloud detail iirc

UV ofc is where it’s all at. But you can get a little detail in IR850.

[cursive inlet]

Yeah thats what I find interesting, some sometimes even get detail in rgb, and others get almost nothing when shooting at even 1 micron.

I think maybe its just the atmosphere of the planet changing

[somber stratus]

Yeah it’s seeing dependent. I got some detail in visible light when I had really good seeing

Boost the saturation and the B channel has a tad of detail

Much like violet filters, just less contrasty

[cursive inlet]

For uv I have the w47 and ir block ready, can't wait for april and the summer.

[somber stratus]

Yeah I have the optolong Venus-U

350nm peak transmission

Will run it with the 462MM

[cursive inlet]

nice

[somber stratus]

Seeing will be poo poo though

[cursive inlet]

Smaller wavelength so it hits more particles right?

Idk atleast I always thought of it like that

[somber stratus]

Think it’s more the fact shorter wavelengths have a higher effective refractive index so the density variations in the atmosphere cause shorter bluer light to bend more.

Added up, causes more variation in the path taken by the light and hence worse seeing

iirc

[ruby tartan]

Perfect for Venus, another filter I will buy next year

[somber stratus]

Much akin to this. The blue is effected more & bent more

Hence density variations (that cause variations in refractive index, similar to the prism above), has more of an influence over bluer light

[cursive inlet]

idk I was basing it off that we can only image individual atoms in xray light, so like the smaller the wave the the more it was to pass through, like for example how radio can pass through building because the waves are massive.

[somber stratus]

possibly related to that too, not sure

[cursive inlet]

But the adc should remedy this no? Atleast a little bit.

[somber stratus]

Not to do with that. That’s a different effect, although similar looking.

[cursive inlet]

oh yeah thats right

[somber stratus]

Density variations in the atmosphere average out more or less, so it’s unbiased which way the light is bent. Imagine 1000s of prisms in a row, randomly placed. The light takes a seemingly random path, with the blue light being more “all over the place” so to speak. The red will take a straighter path.

And (the red light) is hence less effected

[cursive inlet]

Because it hits less of the "prisms"?

[somber stratus]

No, more the fact it is bent less by each one

[cursive inlet]

Hmm interesting

[somber stratus]

Less influenced by the prism’s existence

[cursive inlet]

What IR filter do you use for Mercury?

[somber stratus]

850 usually

Daytime observing

[cursive inlet]

it rotates extremely slowly so I would imagine the integration can be as long as you want

[somber stratus]

correct

but you're limited to how long you can shield the scope from the sun for

or how long after sunset you have to image before Mercury sets

[cursive inlet]

How long do you integrate for Venus? The planet itself spins slowly but the clouds move.

[somber stratus]

clouds move incredibly slow too iirc

you can do about 6 hours if need-be, but you'll never get that long to image it while it's high in the sky

[cursive inlet]

https://www.cloudynights.com/topic/514231-venus-clouds-animation/ ?

[somber stratus]

oh damn

didnt know that

[cursive inlet]

It seems they move a bit faster, maybe depends on the conditions?

seems to be a very dynamic planet

Idk why I just find Venus imaging so fascinating, everyone finds it so boring but its just fun to see Venus and Mercury in the sea of thousands of Jupiter and Saturn images.

Anyways I really enjoyed this convo thanks for the knowlege bomb @somber stratus

[somber stratus]

agree, just hard to find a good time to image

esp if you live far north or far south

Venus' favourable apparitions are rarer for these locations

[cursive inlet]

I've had success during daytime hours

[somber stratus]

yup, same, but seeing is rarely good due to convection

unless you live on the coast

Ground is too hot

[cursive inlet]

yeah and my scope gets so hot

[somber stratus]

yup, tube currents

pain

Merc during daytime. Single stack

kinda noisy

[cursive inlet]

That crater is amazing

[somber stratus]

Venus daytime

was 20 deg altitude

but luckily IR850 and being 1' 03" across helps

[cursive inlet]

I've seen someone online do and image at basically opposition, like a ring of fire

[somber stratus]

this was last apparition. Poorly placed for northerners. Jan 4th

[cursive inlet]

similar to an annular eclipse

[somber stratus]

yeah, 2020. These are rare. Has to come insanely close to transit

2028 will be close ish

[cursive inlet]

Took this Venus during summer with my phone but it was before I got serious with planetary.

But man it wasn't until I imaged in the snow for the first time last month when I started to appreciate how comfy doing astro in the summer is.

ffs i gotta run back inside in between captures to warm my hands

All the mittens are either too fat to do stuff or they are too thin to be warm

Anyways thanks again @somber stratus

[coarse aspen]

is it possible to do a long exposure of venus?

to get both sides

[somber stratus]

no, you need a specific 1050nm filter for that

[ruby tartan]

Was it difficult to find him? I only managed to capture him at twilight, Venus too, I never found them during the day

[coarse aspen]

ive never seen venus in the daylight

i have seen mercury at sunset though

[somber stratus]

Venus is easy, Mercury harder

i use GoTo for Mercury

align on Venus or the Sun/Moon

then slew

[cursive inlet]

I think he meant like the clouds not the surface, sort of like how you can expose longer for the moon.

[coarse aspen]

actually no, ive seen it in the morning hours when the sky is blue just before the sun is up

[somber stratus]

There is nothing for it to reflect. Other than star light and planet-light

not like it has a Moon

1050nm detects IR reradiation, that's why that works

[coarse aspen]

That makes sense

[cursive inlet]

Kind of surreal seeing a star in the finder scope during the day.

[coarse aspen]

We can only expose long to get both sides of the moon because of earth glow

[cursive inlet]

Yeah I also thought so

[somber stratus]

correct. Venus has nothing to light up the dark side

[coarse aspen]

Sirius is visible for quite a while before sunrise, I was surprised

[somber stratus]

Sirius is visible in my main scope during full daytime

[coarse aspen]

I'm speaking of naked eye visibility

[somber stratus]

ah yea

[coarse aspen]

Though that is surprising I didn't think you could see it during daytime hours at all

even with a telescope

[somber stratus]

Venus is naked eye visible in daytime. You just need to look at exactly the right spot in the sky

[coarse aspen]

Jupiter is too, but same as venus you have to know where to look

I found it with my telescope and looked through the red dot finder so i could know where to look in the sky

[somber stratus]

Not full daytime naked eye? Maybe near sunset

i'm talking midday

[coarse aspen]

oh

I was talking about before sunset, not too long before though

[somber stratus]

this at 1pm/2pm^

[coarse aspen]

ah, I was doing it at about 4pm in the winter so an hour before sunset

[cursive inlet]

Fr?

[somber stratus]

yeah, i've seen it myself. You need it in crescent phase when the magnitude is brightest at -4.5

not gibbous.

-3.7 is too dim

need excellent transparency too

ISS is visible in most finder scopes during daytime too. I tracked it that one time back in August. Sun was up.

[coarse aspen]

Ah speaking of Venus I remember a time not too long ago, a few weeks ago? It was about 6pm the sun had gone down long ago, you could still see a little bit of the orange horizon and there was a bright white star. I checked Stellarium because I thought it was Venus and according to Stellarium nothing was there

It was very close to the horizon

It wasnt moving, and it was visible for a while so I concluded it wasnt a plane

Any ideas?

[somber stratus]

Few weeks ago could be Venus

[coarse aspen]

I have a picture

[somber stratus]

otherwise a plane or satellite reflecting sunlight

[cursive inlet]

Do you do the iss at the same image scale as planetary or lower? Like in terms of barlows and stuff. I would imagine it would be hard to track with the same image scale.

[somber stratus]

Lower, need the FOV

tracking is meh

f/8.8 typically, 2x barlow, no ADC

[coarse aspen]

5

[somber stratus]

3600mm

[coarse aspen]

December 3, 5:47 PM

What is that?

[somber stratus]

was it moving?

[coarse aspen]

No

[cursive inlet]

@somber stratus whats your arc second per pixel ratio for planetary?

[coarse aspen]

Mercury below the horizon barely at that time

[somber stratus]

could be it, but it's in opposite direction

[coarse aspen]

Yeah

That's what im thinking

because the star was following the sun

[somber stratus]

8750mm f/21.5, 0.068"/px

[coarse aspen]

mars wasnt in that part of the sky

Theres a chance it was mercury if stellarium was off by a little bit

[cursive inlet]

Wow thats a lot

[somber stratus]

got around to the timelapse on this night

nice cloud dissipation lower left

Colour variation is due to dew formation

[lunar hamlet]

Wowowowow

[ruby tartan]

Mercury and venus

[main flume]

moon

[turbid plume]

Just incredible

How long is that Timelapse?

[somber stratus]

2 hours

[normal forge]

I have the OCAL Pro and i can tell you, it is not easier than anything else.
There are some requirements to collimate correctly with that thing.
If anything is not 100% in line before starting - collimation will be off.

[barren dune]

Yeah i dont like the ocal its not that accurate I use the catseye triple pack set and the autocollimator allows for extremely accurate collimatiob

Bad seeing lastnight also my horrible mars shot

I removed the rind on mars with eliptical marque and select inverse the levels to black out the rind will redo it later bcus it looks goofy

[onyx garnet]

what are you using?

[silent star]

A frickin 60mm telescope and my phone

[somber stratus]

indeed 🥚

[normal forge]

what scope do you use?

[remote star]

took these with my dob last night

I have a 2x barlow on the way so hopefully I'll get better resolution

[heavy mirage]

The movement of those clouds is nuts, almost looks like it was taken from space

[topaz elk]

got some details on mountain

[hasty hull]

Crazy shot

[fading plume]

Crap day moon

[near quiver]

Man you forgot the #1 rule of lunar

[fading plume]

Technically it was after sunset

[near quiver]

You don’t post an image if you can see a cunrom image on the same page

[fading plume]

Lmao

[near quiver]

It will make every image look bad

[ruby tartan]

Sunset and Venus

[coarse aspen]

Facts

Cunrom lunar god with an 8"

[near quiver]

I got what I think is some good lunar data last night but I haven’t gotten to process it because deep sky stacker has been running all day

[near quiver]

Does anybody know how to fix the purple in my Jupiter?

I spent like 30 minutes and I couldn’t color balance it out

[hasty hull]

Were you using a uv/ir cut filter

Not using one can make colors hard

[remote star]

is it visible in the raw data?

[near quiver]

no, ill look into that

[remote star]

oh yeah you should definitely get a filter then

[hasty hull]

That’ll help a lot

The purple could be a uv leak or something

What cam did you use @near quiver

[near quiver]

asi224mc

[remote star]

I believe that one needs the filter for optimal results

[hasty hull]

Definitely

Yeah it doesn’t have a built in uv/ir window so filter is needed

[near quiver]

ok i kind of knew that but i was hoping i wouldnt have to spend any more money lol

[remote star]

I think I also read somewhere that you can also get a sharper image with an ir cut filter because of the focal point or something

not sure how true that is though

[hasty hull]

Yeah it’s annoying but a good investment

[hasty hull]

I think it would reduce ghosting effects and such

[remote star]

ah

I wonder if I should get one for my 178mc

I'm pretty sure I don't need one

but I've seen people use it

[near quiver]

holy crap they are way too expensive

[remote star]

yeah they're like 50 bucks

well from zwo it's 22$ but you'll need to pay for shipping from china

[hasty hull]

I forget how much I got mine for, definitely under $50 tho

[near quiver]

i can probably find a used one on cloudy nights for decently cheap

[remote star]

seems like it does affect it a bit

[hasty hull]

https://www.highpointscientific.com/optolong-uv-ir-cut-astronomy-filter-1-25inch-mounted-uvir-125?utm_source=google&utm_medium=cpc&utm_campaign=616374405&utm_content=30864986310&utm_term=&gclid=CjwKCAiA2L-dBhACEiwAu8Q9YOfBifKhSJWq-PAVpybaNdhFzGpx2L5tyXgZugcRJ82S85EM3onSrRoCaOgQAvD_BwE yikes this went up I think

[near quiver]

everything went up

[hasty hull]

[remote star]

yeah my dob went up by like 200eur since I bought it

[hasty hull]

[near quiver]

Mine went up $200 before I bought it

[hasty hull]

I remember when I was looking like 2 years ago, you could get a new 12” dob for $700 but now they’re like $1200

[remote star]

lmao that's almost as much as I paid for my 8"

[hasty hull]

[near quiver]

I like watching Ed Ting videos and he says “buy an 8” dob for $400” mine was twice that

[hasty hull]

My 6” was like 375 and now it’s well over 500 I think

[remote star]

actually there is a store near me that sold it for like 420eur which is not too bad

it's gone up in the last month though

but I'm glad I bought mine when I did because in a few years for 650$ you'll probably only be able to get an astromaster

[topaz elk]

no you don

[remote star]

yeah that's what I thought

your shots are fantastic btw

[topaz elk]

its built it

kinda annoying if you wanted to do ir but its whatever

[remote star]

yeah

it's a great camera though

has anyone here ever used AsiStudio to stack and process their images?

[topaz elk]

thanks

[barren dune]

@normal forge 14in dob

[remote star]

wonder if you can get the blue lake with that setup

[barren dune]

What ir filter should I get for lunar

@remote star i have

[remote star]

awesome

[remote star]

always wanted to try it but I doubt my 8" dob can do it

[barren dune]

Screenshot from my ig

[topaz elk]

all 8" dob can do it

[barren dune]

My friend got it with a 6in

[remote star]

that is insanely clear

[barren dune]

Its alr

[remote star]

I mean

[barren dune]

I still need to redo it when I collimate

[remote star]

I haven't seen a single shot where it's that large

[remote star]

collimation is honestly the one thing that scares me

I've had my dob for a month now

and I have no idea where to start

[near quiver]

It’s easy

[remote star]

pretty sure I need some sort of collimation eyepiece right?

[topaz elk]

yeah

i wouldn't trust a laser if its cheap

[remote star]

😳

60 eur for a cap with a hole in it

[topaz elk]

@remote star i think the best gain is around 200 for the asi178mc

[remote star]

I don't usually keep track lol

[hasty hull]

I’ve gotten it with my 6, not great and I wouldn’t say it’s resolved but it’s there

[remote star]

but I like to shoot with a lower gain because I can easily boost the brightness

otherwise my image gets overexposed

[topaz elk]

if you can shoot at 200 gain you can lower the exposure time

[remote star]

I'll try it at some point, thx for the advice

[topaz elk]

this is my take on Ina with an 8"

[remote star]

hopefully my barlow doesn't take too long to arrive

[remote star]

impressive

you can even make out the shape

[topaz elk]

ina is pretty easy when you think about it

since it's like 2 by 1 km across

[remote star]

oh

[topaz elk]

8" with 2400mm FL should be able to resolve 1km on the moon

[remote star]

I thought it was smaller

I'll definitely try it then

[topaz elk]

almost 3x2 km actually

[normal forge]

@barren dune can you go for that region at any time?

i had a roguh time capturing fine details with a not good collimated 6" sct but i still like it.

the upper area!

[topaz elk]

debayer issues?

really sharp pic tho

[fading plume]

data and pic

[hasty hull]

bro

your moon pics might be my favorite moon pics

[nocturne zinc]

Godamn, what do you use to make it so sharp?

Compared to mine🤣 this is taken on a phone through eyepiece with no edits

[normal forge]

yeah... OSC suck on lunar imaging. really hate this. have this now and then, not sure why. bayer pattern is correct, software works correct. i don't understand it.

[normal forge]

and to be honest, i don't see them on fullscreen @ 100% image size, but they are there when resizing the image to < 75% or so. on my 32" 1440 screens, no artefacts at all.

even when i open this image here in the browser @ 100% -> no debayer artifacts

[summer field]

these artefacts can be easily removed with a Fourier transform

[normal forge]

i don't know anything about that

[summer field]

these are high frequency artefacts (~1-pixel width lines), they will appear as bright areas close to the edges in the Fourier transform. by darkening those areas, you will remove them without touching useful data (planetary images tend to be oversampled so there is usually nothing at high frequency to begin with)
You can use the Astrosurface software for that (maybe another software can do this too), the Fourier transform is in the "filters" menu, you can directly use the HF presets to remove the high frequency part

[sharp ridge]

interesting, thanks for this info

[somber stratus]

doesn't seem to do anything on my data

[normal forge]

will try the next days! 🙂 thank you!

[summer field]

May I have a look at it ? It will only work in a few specific cases where the artefact's signal is visible in the Fourier transform

Another example, it's not perfect, but it kinda works

[somber stratus]

oh no it does work, but it also stretches the data too. Reduces contrast

adjusts the offset for some reason

[summer field]

yeah, it adds an offset

I usually deals with it by applying a negative offset until it matches the original image (or just using the BW-point function on a dark part of the image)

[somber stratus]

BW point is easiest for sure

[near quiver]

Does anybody have recommended 1.25” uv/ir cut filters?

[hasty hull]

I use one from Optolong, works pretty good

[near quiver]

https://www.highpointscientific.com/optolong-uv-ir-cut-astronomy-filter-1-25inch-mounted-uvir-125 like this one?

[hasty hull]

Yup

[near quiver]

Ok thanks I’ll probably buy it

[barren dune]

Anyone know what filter tp get for lunar imaging

[topaz elk]

very helpful, thanks a lot

[near quiver]

Update: I bought it @hasty hull should be here in a couple days

It’s funny I had been wondering why my phone images had better colors than my dedicated camera images but that makes perfect sense

[near quiver]

I mean from what I understand you don’t really need them but if you really want one you could just get a neutral density filter to make it darker

[topaz elk]

IR filter if you wanted to do IR

[barren dune]

Ty@topaz elk

[topaz elk]

np

[hasty hull]

Like 3/10 seeing but here’s Jupiter from like 20 mins ago, sun 16° up

Daytime is a lot of fun

[hasty hull]

Native 1200mm

[barren dune]

Nice jon

Job

[remote star]

trying to get uranus rn

raw video is fine

it looks clear enough

but asi stack is ruining the whole thing lmao

gonna try using autostakkert

[remote star]

final result

[proper oyster]

first pichure i manage to get out of my 8inch telescope

had to fight against my phone for the focal

[wary siren]

all the planets i've captured so far with my scope (Orion xt8, asi120mc-s, 3x or 2x barlow)

[barren dune]

2k frames on ina lastnight mid but its there

[normal forge]

how do i capture color images from the moon surface with an OSC?

is there a SOP for that or any guide?

[topaz elk]

from what i've seen ppl got color from moon surface with their DSLR

and blend it with the data they got from the planetary cam

hopefully that helps

[normal forge]

i won't buy a DSLR for some lunar shots o_O

[near quiver]

I mean you could just shoot normally and saturate it a lot

[topaz elk]

yeah but the color is not that great with planetary cams
