Planetary Imaging

[green pebble]

How is it hateful, i had seen worse profile texts and they had none warnings

Ok back to the theme

[ripe shard]

Let's just forget about that

[hasty hull]

Idk what your thing said i was just using the convos context

[green pebble]

Dude

[hasty hull]

🤔

[green pebble]

Ok bye im done

[hasty hull]

cya

[ripe shard]

Bye

Stay safe

[random pecan]

95% stack vs 25% stack

kinda interesting

[safe compass]

Learn to accuse the right person next time, and I apologize for causing this mass chain of the crazy

[green pebble]

Oh yeah, sorry

[proud mulch]

[hearty fiber]

Bruh wtf is this

[safe compass]

Dude stop.

[hearty fiber]

Also psa: please don't use the "I have freedom of speech!?!!" Argument whenever someone tells you to shut up. People can legally ban you from their discord server or whatever for literally any reason, including if you say something they don't like. Using the first amendment usually just makes you sound like you don't know what you're talking about.

[proud mulch]

I was just continuing what he was about to say 💀

This is 1984, cameras everywhere

Also this is a planetary imaging chat 💀

[thick heron]

Top quality discussion. 💀

[steep apex]

Bro what happened while I was sleeping 💀

[safe compass]

💀

[proud mulch]

💀

[proud mulch]

Some mf was talking about how he warned and then started bickering about rights 💀

I mean yes you have rights but this is a planetary chat not the outside world💀

[cursive inlet]

Nothing but the best from #1019937457095065731

[green pebble]

Yeah lets get back to planetary imaging and not talking about rights😄

[thick heron]

We should argue about something less controversial.

AI sharpening

[safe compass]

Too controversial.

[proud mulch]

[coarse aspen]

I think if someone made an AI for planetary decon it would be good

BlurX kinda works on planetary

It gave really good details, but it made the gas giants look like rocks, not. well,,, gas giants

[heavy mirage]

Topaz denoise ai is something I've been considering investing in. Not really sure how worth it would be

[livid sierra]

Just don’t use it for planetary lol

[heavy mirage]

my brother has it, and he ran a couple of my images through it and it did a pretty good job. I think it can be useful for planetary especially if it's used for a 'final' denoise after all your sharpening and other processing is done including manual denoise

[coarse aspen]

I can see how topaz might be useful, planetary images usually arent that noisy compared to DSO so less chance for it to imagine details?

[random pecan]

@frozen root have you ever tried making a denoise ai for planetary

[thick heron]

I theoretically have a dataset for wavelets since I usually save them, just not sure it’s worth it though. All AI software I’ve seen have sliders to adjust their strength, which is not any different to how wavelets work so why throw in an extra step?

A more complete solution of sharpen, denoise, derotate, and color balance could be interesting though.

[somber stratus]

Colour balance is the main thing that would be neat to automate

imho

As changing transparency and dew levels changes the raw data, so it's hard to match processing every time.

[frozen root]

Uhhh

I’m more focused on sharpening for dso’s but I can do that

FYI it’s super easy to create sharpening and denoising models for planetary imaging

Simply because there’s a high contrast medium making it easier for the Convolutional layers to identify and isolate features

[frozen root]

the sliders indicate the individual algorithms implemented within each Cnn layer its not really the same AI looping itself

[random pecan]

Id love to attempt but I’m rusty on my programming skills

[frozen root]

i got u

ill try it when im done with sharpRnight

[coarse aspen]

that the name you decided with?

[frozen root]

ye

I like it a lot

[coarse aspen]

nice

[random pecan]

id love to see it

[past ore]

You did not get this right this is like Hubble or something

[heavy mirage]

Do you have enough frames for a short animation? I think you may be able to see that festoon moving right below the ring

[sharp ridge]

https://media.discordapp.net/attachments/570687129118703637/1136544490333667389/2023-08-02-1745_5-KL-RGB-Sat_lapl6_ap40s_pipp.gif

this is from about 1hr previous, that image sequence is 3 frames

[lean hearth]

That’s so wholesome

[sharp ridge]

yeah

too noisy

[heavy mirage]

Use de-field rotation script?

You can kinda see it

Nice work!

[sharp ridge]

i dunno how to use it

this is the sequence of 3

[heavy mirage]

Just for an experiment, maybe oversharpen with a larger wavelets size to bring it out a bit more? I know it won't look at nice but might bring out some of those larger surface features

[sharp ridge]

yeah ill try that later

i still got my jupiter animation to stack and process

[hasty hull]

that’ll be wild

[random pecan]

You’re real close to Damian peach level

[random pecan]

That’s ridiculous man

I envy you

[bleak rose]

Fly TO saturn and take a picture

Should help

[lime veldt]

WHAT

no way bro

[glad mason]

hey guys do you know what is the best planetary telescope for around 300-400 dollars

[lime veldt]

just for visual or also some astrophotography

[glad mason]

astro too

[lime veldt]

let me check

are you looking for something computerized or just the scope

@glad mason

[glad mason]

scope

[onyx garnet]

Holy shit

[lime veldt]

how far over the $400 limit can you go

[glad mason]

around 450

[lime veldt]

460?

[glad mason]

sure

[lime veldt]

https://www.bhphotovideo.com/c/product/1666170-REG/sky_watcher_s11600_classic_150p_dobsonian.html/?ap=y&ap=y&smp=y&smp=y&smpm=e_f83mkz_uar&lsft=BI%3A6879&gclid=Cj0KCQjwoK2mBhDzARIsADGbjepHko_HaqWrDY27NK5mt2tuTUy_lZEI5FHxDYHT11PvkLxrn-S-5iYaAh8EEALw_wcB

6" dob

that might be kinda hard to set up a tracking mount for though

[glad mason]

oh ok thanks

[lime veldt]

https://www.ebay.com/itm/234951428368?hash=item36b4324910:g:eFMAAOSwE1dkJOH1 i also found this, its used though

[glad mason]

ok thanks for the info

[lime veldt]

i have this same scope and its pretty good for planetary. it also has built in tracking and goto system

[glad mason]

ohh

is newtonian better than refractors?

[lime veldt]

for planetary im almost positive reflectors are better than refractors

[glad mason]

oh okk

[lime veldt]

if i were you i would save up and get something bigger than a 6 inch

[tidal crow]

8 or even 10

[lime veldt]

^

especially for dobs you need bigger scopes

[tidal crow]

I would get a 14 inch dobson that i can barely move inside and out at clear nights

[lime veldt]

lmao

[lime veldt]

4" sct has more FL than a 8" dob

[heavy mirage]

You open it in vs code, then set the directory to the directory of your stacks. And set an output folder as well.
You also have to set your location and the time you want your frames to be field derotated to, in utc

Then you navigate to the folder your python script is in with the terminal and run the python script

I would usually do field derotation manually with davinci Resolve. The script can be somewhat wacky but it gets it close, probably due to the time frame as!3 generates

[thick heron]

That script has a severe lack of sys.argv.

[eternal solstice]

bruh what happened right there

at least the chat is normal now

[glad mason]

the thing is in my country they dont really sell 8 inch dobs and most of them sells celestron refractors and small newtonians so thats kinda sad for me

[lime veldt]

you can’t order?

[glad mason]

shipping cost like $200

[lime veldt]

Ohh rip

[glad mason]

also taxes

[heavy mirage]

Yeah, you're right. I might play with it a bit to add some argv

Prolly will just ask for user input

Through console

[fading plume]

Both seeing forecasts say good things for tonight. Dont have a big day at work tommorow so might stay up hm.

jetstream is changing directions right over my house though

it does change a lot in the +9 hour forecast

actually this is 1700 hours lol

this is right

2 am. Saturn peaks at 1 ish

[fading plume]

Wonder if i can resolve this

[uncut glade]

What aperture you got? I've seen it done before but it's tough

#older_system_pics message

Nevermind People do it with 10 inch apertures, you got this

[onyx garnet]

raw data?

[sharp ridge]

converted from ser to mp4

[onyx garnet]

how in the shit
it's so good

[sharp ridge]

astrosurface planetary stacking

[fading plume]

Blur

[green pebble]

Dude the seeing must have dissapeared

Beacuse thats way too much detail for raw data

[coarse aspen]

This is so good it makes me feel like Jupiter is right there infront of me

Could you get that view of Jupiter doing visual through a 16"?

[thick lotus]

Few more years and Saturn gets high enough to actually image decently up here... it has been a long wait

[eternal solstice]

that is.... RAW DATA

[somber stratus]

lol/10

[sharp ridge]

visual is similar

[coarse aspen]

i thought so if you had the magnification for it

thats crazy

[steep apex]

Where do you buy this good of seeing

[cursive inlet]

i'll send you my plug

[uncut glade]

Send that my way too I need some saturn time 😭

[uncut glade]

Speaking of which

Bro why is Saturn so sim

Dim*

400 gain at 40ms exposures and it’s peaking at 40% histogram value in red

That’s a lot of 4s but it’s true

[proud mulch]

It’s far away and smaller

[green pebble]

I just found out that my secondary mirror was out of collimation

@remote dragon you were wrong, that wasn't coma. It was the secondary mirror

[deep island]

Full moon mosaic.
114/900mm, eq3 + Sv905c. 6 panels

[remote dragon]

nice

(this is the planetary forum tho )

[green pebble]

Thats the data you processed in siril

Oh yeah

I know

[remote dragon]

i mean it's a planetary nebula

so i guess it counts?

[green pebble]

I guess so yeah

[remote dragon]

the gradient might have been collimation and better collimation does help with coma

but you will still have it

[green pebble]

Ik

I collimated the scope

Imma try it again

[remote dragon]

good luck

[green pebble]

Thx

[fading plume]

idk why i thought venus inferior conjunction was on the 7th. Its on the 13th.

I have far greater hope of catching the 0.9% phase with weather

[weary jungle]

Would anyone have any answers. Recently I have been struggling with getting clear shots of the planets. I am using a C14, ASI462MC,2X Barlow on a CGEM. It might be a seeing issue or something else just wondering what I should improve.

[proud mulch]

Weather

[weary jungle]

So just hope for better seeing? How important is an ADC?

[heavy mirage]

@weary jungle Adc would help reduce the red and blue fringing caused by refraction of light by the atmosphere. It works by optically aligning the red and blue wavelengths, and is especially useful. Your data would be slightly sharper and less blurred

But ultimately transparency, seeing and collimation have the largest factor. In the video you sent, it looks like poor seeing.

Also, you have to let the scope and optics reach ambient temperature, this will help reduce turbulence in and around your scope, generally takes 45 mins to 2 hours depending on the telescope size.

[weary jungle]

It is on a permanent peer on a roll off shed and this was after a few hours so I don’t think temperature was the big problem. And thank you I will look into getting as ADC and keep hoping for better seeing. This Ohio weather is definitely tricky. Also I don’t know how long it’s been sense collimated so I will give it a look

[heavy mirage]

Ah gotcha, that's neat. Wildfire smoke makes a big difference too, even if it's thin basically makes your image blurry even if seeing is really good

Astropheric does a pretty good job of mapping the smoke from wildfires

I collimate before each use, but I also am not on a permanent peer lol

[weary jungle]

Yeah makes sense that’s smoke has been a big problem recently. Well I really appreciate the help I will make sure to keep sharing photos and my progress as time goes on.

Oh also my Barlow I am using is unbranded and I am not sure how the quality is. Would you happen to know if a 3x or 5x would be better and any recommendations?

[summer field]

A x2 is already a good combination with a c14 and a 462 with 2.9µm pixels 🙂

[weary jungle]

Ok thank you😊

[summer field]

Do you have an UV-IR cut filter ?

[white prawn]

Unbranded may be nothing more than taking up space. If it's plastic, it's junk. I purchased a 3x Barlow for $50, I have 2 - 2x Barlow lenses that came w/ different sets, and I purchased a 5x Barlow for $150. None of them are junk, all are metal and multi-element coated lenses.

[weary jungle]

It seems to be of actually pretty decent quality it isn’t plastic and fully metal. The lenses seem to be good quality to but unfortunately the box was blank. I might invest in a good one soon though. Any brand reccomendations?

[white prawn]

Maybe you're lucky? I bought my 3x from Amazon, it's an Astromania and threaded so it can be set on a DSLR T-ring adapter. It was in a white box, label was a sticker. In fact the best Barlow I have came in a white box, the brand is Orion and I bought that from telescope.com. The 2x that I have both came in a kit, one was from Celestron and the other was from Svbony. Thing to consider is that except for the 5x none of them are "specialty, amazing, high end otherworldly quality" Barlow lenses like the Celestron LX or Lumos. However, they are of sufficient quality that I did not at all mind paying the price I did.

The kits were between $50 and $100.

[steep apex]

I’m gonna do first light on the ISS with my new camera

I need help with the settings though

[coarse aspen]

Nice

[ruby tartan]

💀 💀 💀 💀

Bruh

[coarse aspen]

exposure about the same as venus

[steep apex]

Like gain and exposure ms settings

[coarse aspen]

why is it red? white balance or smoke

[ruby tartan]

I don't know what's going on with that telescope

[ruby tartan]

White balance

[coarse aspen]

smoke turns my stars red

[steep apex]

What happened

[ruby tartan]

First telescope test in June

[ruby tartan]

today

😠

[ruby tartan]

I don't know, I've been having this problem for a while, I collimated correctly, it's collimated but it stays that way

[steep apex]

For capturing the ISS with firecapture, how much storage does the video take on average?

[ruby tartan]

I'm running out of ideas to solve this

[white prawn]

Get a "Make image not be dog turd" filter.

[ruby tartan]

Throw that telescope in the trash

[proud mulch]

Also, use cutout

It makes it go from 25 TB or some high number idk to under 300MB

And use Jupiter as reference

Also red filter

[fading plume]

Red filter on a colour camera ah yes

[proud mulch]

Who cares

All you need to do is set it to black and white

[weary jungle]

I have decided on the X-cel but am wondering with my setup if a 2x or 3x would be more beneficial

[fading plume]

Physics and common sense

IR is the only one that makes a difference. Just extract red channel if shooting OSC.

[proud mulch]

Well the thing is I don’t mean it like a red channel

In all my ISS photos I used a red filter

And you know how I am with ISS

[fading plume]

IR or red? A red filter only makes an image worse. The CFA is already there. You are simply dropping signal further.

Unless your filter cuts out more of the higher frequency light than the CFA does it won’t affect anything. The reduced SNR makes it worse

Plus with your resolution you defo aren’t seeing limited

[sharp ridge]

i would just use the osc data to produce a color image

[fading plume]

You are far more SNR limited lmao

[sharp ridge]

also this

[fading plume]

This is my ISS.

[steep apex]

I might not do the pass

[fading plume]

Why

[proud mulch]

Dumbo

Dingus

Image it

Better a failed shot than no shot at all

[steep apex]

Ok

[proud mulch]

But remember

0.5 ms or lower, medium to high gain, idk about gamma

[steep apex]

I wish Venus was still here

[proud mulch]

Just focus on a bg star

[steep apex]

Clouds are rolling in

[proud mulch]

Oh well be out there when ready

[steep apex]

Ok I’ll try

[proud mulch]

Just try comparing settings to Jupiter

[steep apex]

Should I even image it? I have no experience with my camera yet

[white prawn]

https://tenor.com/view/doitdoit-gif-27670853

[fading plume]

🤏

[uncut glade]

When shooting on an alt-az mount, does field rotation affect stack clarity? Or are pipp and autostakkert able to remove those effects?

[thick heron]

Astigmatism? What does it look like inside and outside of focus?

http://www.loptics.com/articles/starshape/starshape.html

If it is, the primary mirror clips needs to be loosened.

[somber stratus]

Looks like garbage seeing to me.

ADC helps of course too

[weary jungle]

Ok do you have any ADC brand recommendations?

[somber stratus]

ZWO/Pierro astro/Omegon

whatever

[ruby tartan]

Mild

[ruby tartan]

I did this when I put the telescope away, today I'm going to collide it again and I'll test it over the weekend

[white prawn]

What does colliding a telescope do for it?

[ruby tartan]

Collimation***

[white prawn]

I kinda figured, but you have to admit the thought of a form of percussive maintenance on the telescope that would actually make it work better is kind of amusing.

[white prawn]

Jupiter and Saturn are starting to show up, esp. Saturn showing up on the PM side of things, but they're low on the horizon rn. When will it be better to image them?

[green pebble]

Collimaton is basicly shifting the mirror in the newtonian scope so the light reflects perfectly into our eyes

[proud mulch]

planetary nebula

[green pebble]

Whaaaattt

Is this ft

Fr

With your neptune c

Damn that is nice

Wait how old are you again?

Dude thats awesome

Im suprised

But this is planetary imaging

Oh yeah its a planetary nebula, it counts

[proud mulch]

C-II

[proud mulch]

A youngen

[green pebble]

Oh yeah sorry

13?

Wait is there stacking and processing

I know its not a tracked mount

[proud mulch]

Yes

And here’s a better process

And another one with slight changes

[green pebble]

Dude thats nice

Can you do backround extraction in siril, it will give you darker backround

[green pebble]

@proud mulch I did the backround extraction in siril for you. looks better, doesnt it

[proud mulch]

Ok

[gray orchid]

Nice planet

[proud mulch]

ary nebula

[fading plume]

This is planetary chat. Not deep space chat.

[ruby tartan]

💀

If it's round it's a planet

[proud mulch]

I can make an immature joke here but I choose not to

[ruby tartan]

Do it

[proud mulch]

No

[ruby tartan]

[weary jungle]

With a C14 do you guys recommend a 2x or 3x Barlow I want to get a X-cel LX Barlow. Just don’t know which magnification. The camera will be a ASI462MC

[proud mulch]

4x

3x

[weary jungle]

Also do you guys think a Barlow or a ADC would be more important to ge first with a limited budget

[proud mulch]

I said 3x

Adc?

Oh

Astrospheric thingy corrector

[weary jungle]

Alright ill get a 3x then

[hasty hull]

Barlow, you won’t really need an adc if the target is reasonably high up anyway

[weary jungle]

and yeah

yeah i havent had a big problem with atmospheric dispertion yet

[proud mulch]

So get a Barlow

[weary jungle]

alright ill get the 3x then thank you.

[proud mulch]

Ok

Gl with your space stuff

[weary jungle]

Thanks man If we get clear skies I will post some pics on the server around here

[proud mulch]

We?

[weary jungle]

sorry meant I

[sharp ridge]

2x Barlow

Or 2x + adc

[weary jungle]

I was thinking that might be better sense the f/ratio of the C14 is already very high

Do you think that will yield better results?

[sharp ridge]

Yeah

You want 5-7 x pixel ratio

So 2.9x7 = F/20-25

So 2x or 2.5x is preferable 🤭

[weary jungle]

Alright thank you so much I will purchase one soon. Also do you recommend the ZWO ADC as well?

[sharp ridge]

Yes, even when the planets are high alt they will be helpful sooner or later

[green pebble]

Coma corrector

[steep apex]

ADC is atmospheric dispersion corrector

[green pebble]

[heavy mirage]

crop and upscaled version of Saturn 1 hour time-lapse, I might be crazy but I'm pretty sure I'm seeing some details rotating especially in the region below the ring and about halfway between the pole and equator, very mild but still kinda cool.

[ebon sage]

Daytime

[steep apex]

Yes

[green pebble]

i reprocessed some of my old orion data, 130/900 reflector with my xiaomi redmi note 9 pro, 8sec exposure and 3200 iso handtracked, only processed in siril, no stacking baecuse of skill issue

[steep apex]

Where do you buy good seeing conditions the atmosphere over here is doodoo

[steep apex]

Why in planetary imaging forum tho?

[green pebble]

wrong chanel

channel

[ripe shard]

Why is everyone suddenly posting pics of nebulae on #1019937457095065731

Nvm it's only you

[steep apex]

As soon as I get decent seeing conditions the clouds came

[ruby tartan]

2x

[sharp ridge]

god i keep screwing up the collimation

single 120s stack 50%

[sharp ridge]

collimation or astigmatism

[white prawn]

Gain/exposure?

[hearty fiber]

I doubt that would be causing the issues

It's easiest to see on titan: there are some "spikes" coming out of one side of it that indicate some kind of optical issue

[heavy mirage]

I believe astigmatism is mostly caused by over tightening the collimation locking screws?

[summer field]

or both 🙂 but collimation is clearly an issue here

[heavy mirage]

And perhaps primary mirror clips being too tight is something I heard too

[thick lotus]

Usually too tight primary presents as these very distinct triangle stars

It is not usually the problem with SCT I think

[ruby tartan]

Bro thinks he's damian peach

[proud mulch]

https://tenor.com/view/nasa-nasa-gifs-telescope-hubble-hubble-telescope-gif-10093419

[coarse aspen]

That's not Damian Peach thats Damian Orange

[proud mulch]

Damian 600nm

[fading plume]

Just do it during the day. That’s what everyone is doing.

It’s like 12 degrees from the sun. Pretty easy to spot.

It’s almost naked eye for me, dropped a few weeks ago. But it’s so large and bright in my finder scope.

[proud mulch]

Planet(ary nebula)

[hasty hull]

nah

[coarse aspen]

hes getting into DSO

@proud mulch don't continue down this path... you're going to lose thousands of dollars and you will never financially recover

[proud mulch]

Planets are getting kinda boring rn because of clouds

[proud mulch]

I will NEVER buy a eq tracking mount or a refractor I give you my word

[coarse aspen]

https://tenor.com/view/yoda-you-will-see-star-wars-gif-10677531

[hearty fiber]

Things said moments before disaster

[gray orchid]

Yea you'll get tired of that quickly

[white prawn]

Why would somebody NOT want that equipment?

[proud mulch]

Someone who doesn’t have more money than Elon musk

[remote dragon]

said no dso astrophotographer ever

[onyx garnet]

gonna take scope to the astro store to check collimation for the first time
if it isn't the problem then the uranus-c itself is

[onyx garnet]

I said that 4 months ago
here I am getting a frac/eq setup

[eternal solstice]

flashfoward a year and you have a 10 thousand dollar dso equipment

[steep apex]

As soon as I set up the seeing goes from 7/10 to 2/10

[sharp ridge]

krill issue

[thick lotus]

That makes me imagine great big bonfire burning just below the fov

It looks sort of like the insane wobble you get when heat is escaping pavement when night comes

[sharp ridge]

1/10

i will go back to sleep

[steep apex]

Ok

For the rest of the week the seeing forecast looks bad

[somber stratus]

Roughly where are you based?

[steep apex]

The Hawaiian islands but usually it isn’t that bad, might be this hurricane which is miles off the south coast that brought the turbulence here

[somber stratus]

If you're on the west side of the islands, you'll get turbulence from the high rising peaks. But yeah that hurricane looks nasty

won't help

[proud mulch]

@hasty hull how do you get so much sharper images than I can get?

You have similar equipment to mine so yeah

[hasty hull]

Unsure, could come down to processing styles, collimation etc

[proud mulch]

I was thinking the UV IR cut would be helpful

After all this is what I got at the same time as you did (your image was sharp)

[coarse aspen]

UV/IR helps a lot

ADC and Collimation too I believe

I'm gonna try planetary with my 130PDS

Because I have really good collimation

Just gotta get a Uranus C

[proud mulch]

How much is an ADC?

Oh

Too much

[white prawn]

Yeah, I saw those prices. An ADC is in the category of "I want to take better photos, and I can wait for stuff to be higher in the sky."

[proud mulch]

Can’t

[proud mulch]

Called impatience or rare event happening

[white prawn]

Entirely too relatable. I know Saturn won't be at peak altitude tomorrow but if the sky is clear I'll likely try to image it.

[nova delta]

Or it just doesn’t get that high in your location

[white prawn]

Maybe I'll have to strong-arm my budget. 🫤

[heavy mirage]

Even at high altitudes the adc comes in handy

[coarse aspen]

ADC has a pretty crazy impact on detail from what I've seen

[white prawn]

Folks, is it just entirely unrealistic and too much to ask for a program that can properly do RGB balance/alignment for ALL the planets, ALL the time? Like, 100% actually work?

[hasty hull]

You could rgb balance on Jupiter which is mostly accurate most of the time, and then just manually use the settings it put in for other planets

It’s what I do

[white prawn]

Same here; I'd just appreciate if the program worked instead of me having to give some ham-fisted adjustment.

[heavy mirage]

AstroSurface does a pretty good job at RGB alignment, it's a bit more precise than registax

But rgb balance, registax does a better job imo

[white prawn]

That's the frustrating thing. I need to have at last count 3 different programs to pre-process because each one does at least one function better than others.

[somber stratus]

Yeah Astrosurface is sub-pixel

[somber stratus]

Some of us don't have the luxury of even being able to wait. Planets too low regardless of the time you shoot them.

[livid sierra]

Victim here

[white prawn]

Wow. I'll just say that I really appreciate where I am then. I know I've said it before. What you said just gave me another "oh wow, I didn't realize that" moment. I know that people live in higher bortle areas, and not everyone can compensate or see stuff with naked eye that I can. I didn't think that some people don't get a really good opportunity to image planets that some of us can take for granted will follow a path to relatively easy imaging. Thank you.

[somber stratus]

It comes in swings. We get fairly good winter oppositions at ~60° altitude, but the summer ones are abysmal. Saturn rises to 27° max at the moment for Duif and I for example. I like it though, it's a good challenge for a few years.

Can't say I liked 2018-20 though.

[white prawn]

I suppose I'll stop my whining about Saturn being low over the treetops where I am. What altitude would this be, approx, do you know?

[ripe shard]

+3°

Wait that's the highest it gets

[white prawn]

No, that's early in the evening when it's convenient.

[ripe shard]

Ok

[white prawn]

Later...

I think right now Saturn is highest in the wee morning hours and I don't want to be up that late since my alarms start going off at 5:30. But not unreasonable to see what I can do at 9:30, 10 or so

[ripe shard]

No wait, that's approximately +11.6°

I made the first guess without looking at the stars

[livid sierra]

Stellarium has a feature to show altaz lines and also if you open the menu for Saturn it shows the exact altaz as well as dec/ra coordinates

[livid sierra]

And yes. For example when Mars is at its closest again in 2033, making it 22” it’ll only rise up to 9° here..

[thick lotus]

Well.... to show you something really pity inducing

thats saturn at south meridian :/

[livid sierra]

Shit sucks

[thick lotus]

sorry for confusing E, my stellarium is in Finnish where E stands for Etelä which is south

[livid sierra]

Interesting

[thick lotus]

Sometimes confuses me when hopping between software x.x

[onyx garnet]

me at the equator:

[coarse aspen]

wait actually?

[onyx garnet]

No kidding

[coarse aspen]

you have the ideal area for astrophotography loll

get both hemisphere constellations, planets are really high

[candid flare]

How do you polar allign then?

[onyx garnet]

i don't have a eq mount yet

[candid flare]

Ah

[onyx garnet]

but maybe nina polar alignment or smth

[onyx garnet]

you sure?

I would like you to rethink very carefully

[coarse aspen]

[onyx garnet]

Legit

B7 can be 12 hours away when the customs are really bad

Personally I have been through 10 hours JUST to pass the customs

[candid flare]

💀

[onyx garnet]

Not including actually going to the b7 area

meanwhile people at aus: haha

[coarse aspen]

https://www.cloudynights.com/classifieds/item/344303-price-drop-zwo-atmospheric-dispersion-corrector/

If anyone needs an ADC got one here for a good price

$95

(not mine)

just realized its not much cheaper than new

[steep apex]

Looks like decent seeing tomorrow morning

Hopefully

[proud mulch]

And I thought Ohio was bad

[onyx garnet]

fr dude

[proud mulch]

All I can say, go north to that blue spot

That’s your only hope

[onyx garnet]

bet

sydney?

[proud mulch]

It’s on the island

[white prawn]

Found a advertised on FB. "Planetary Astronomy" Says it gives info on how to view and image planets, and how to use the popular processing tools out there. Advertised for 59 Euro. Anyone know anything about the book and if it would be worth it?

https://planetary-astronomy.com/

[near quiver]

It could be but you can get all the same information online for free

Kind of the same way for any astrophotography book

[white prawn]

Fair enough. I'm willing to pay to have something to sit back and read without being on a computer.

[near quiver]

If you want it go for it

Check the production year though

If its more than a few years old it’s probably pretty outdated

[proud mulch]

Or a star atlas, bro just use Stellarium

[near quiver]

Well a star atlas can be very useful for visual

[hearty fiber]

You can use a star atlas and red light while doing visual in the field and not screw up your night vision. Can't really do the same with stellarium

[thick lotus]

Good star atlas or printing charts with cartes du ciel is essential for visual

Things change quite slowly you see... I still use Norton's 2000 that I got in the 90:s

[gray orchid]

Finally getting back to Saturn, except with ass seeing.

10% of nearly 6k frames, Saturn only around 25 deg high.

Luminance detail from QHY 5L-II-M and color data is from SV105 (w/ same rig)

[thin aspen]

10% if 2k frames at 10 degrees above horizon. Absolute garbage seeing but first time ever imaging saturn

200p classic
Fuji xt2 Dslr 4k 30fps
2x barlow
Should I get a 3x barlow as it was quite small

[heavy mirage]

Very good conditions

Ignore the green halo baaa

[safe compass]

I won't ignore the green halo

[heavy mirage]

Phone camera white balance

[bleak oak]

Tricky question I have a Saturn image with excellent red channel and terrible blue channel, what processing Methode would help?

[somber stratus]

Io?

latitude looks to be about right

[heavy mirage]

Yes, started shooting just as it left behind jup

[sharp ridge]

show the result

[somber stratus]

where are you based also? I wanna check windy.com regarding seeing. Trying to learn what's the driving factors.

[heavy mirage]

I'm at 45N, Salem OR

[heavy mirage]

Maybe 1 stack, if I'm not dead lol

[somber stratus]

wtf 100F on monday for you

[heavy mirage]

Apparently transparency wasn't great according to astrospeheric but maybe that's what you'd want lol

Oh yeah, lol it's gonna get pretty hot

[somber stratus]

Expect similar seeing tomorrow.

[heavy mirage]

That's awesome, I might go for a session tomorrow. Uni and work been pretty busy lol

[somber stratus]

I see why it's good. You have northerly winds atm which don't really go over higher ground. Combined with a weak laminar Jet stream it's lovely. I think if you had westerlies/easterlies you'd get turbulence from nearby mountains.

600m

[heavy mirage]

Are you a meteorologist or something?? Hahaha

[somber stratus]

Nah, just trying to understand seeing. I look at the weather a lot

Tomorrow is indicating 10/10 nearby you.

[heavy mirage]

lets you shoot during the best of nights knowing all these little details

[heavy mirage]

Stop tempting me!

[somber stratus]

Especially if it's clear for weeks at a time.

For me, it's not, so i don't really have the problem of burnout

I just image every night that's clear.

[white prawn]

@somber stratus quick question for you, do you use ADC?

[somber stratus]

Yeah.

I kind of have to.

[heavy mirage]

Wild, Iwould do that when I first started but the times when it's clear doesn't always mean good seeing but I guess you just gotta risk lol

[white prawn]

I just ordered one, I wanted to ask someone who has experience using it. Do you need to do anything special to get focus, like shorten tube or anything? Or was it just plug it into the setup and no issue?

[heavy mirage]

I wasnt expecting very good seeing today, usually I'd base it off the stars twinkling and tonight was very calm

[somber stratus]

It's usually not possible to focus if you have the ADC first. I place mine behind my barlow, but before the camera.

Which in-turn increases effective focal length as the camera sensor is further from the barlow's elements. So look out for this.

[white prawn]

That was the concern I had - increased focal length. I read about that on the ZWO site. But you're saying as long as it's in the right place in the chain of equipment, I shouldn't have any problems. Basically the "at focus" point will be at a different spot on the focuser travel.

[somber stratus]

The only way you avoid a different focal length is to place the ADC first, which usually doesnt focus as you need more in-travel than what's available with most focusers

But it might be different for SCTs for example. I only have had experience with Dobs.

[white prawn]

So: Barlow plugs to focuser, ADC to Barlow, camera to ADC.

I have a Newt.

So, Dob on a tripod

Kinda

[somber stratus]

yup

[white prawn]

Okay, thank you for that. When I read the "extends by 56mm" I got scared. That makes you the second person to say "no worries" and also the one to say that from having used it regularly. Again, thank you.

[heavy mirage]

@sharp ridge here is 1 stack, i'll get through the rest later

[tardy iris]

Hey guys, I’m making an upgrade for my 8” dobsonian telescope for planetary imaging. I currently use a 120mc with a 3x Barlow. I’m looking at either the 178mc or the 585mc with an additional ADC and IR cut filter. Which one would be a better camera for me?

[heavy mirage]

178mc is a good 'budget' option, but you'll probably get better results with the 585

[white prawn]

Can concur with getting results from 585. I was imaging Mars in March, less than ideal timeframe, and can't complain about the results.

[tardy iris]

Thanks guys

[sharp ridge]

i think seeing here would be 9/10

really easy to sharpen

[thick lotus]

Well, saturn will still suck... reaches barely 14 degrees for me which is below treetops but jupiter should be able to get at least something out of this winter, that will be solid 40 degrees when at south meridian.

still bad but not THAT bad

my seeing usually rarely gets above 6/10 though

[somber stratus]

Why is it upside down? You place the camera like this?

I mean the raw stack here.

[heavy mirage]

Do you use the small details and large details slider together in AstroSurface wavelets?

[heavy mirage]

Yes, i usually turn the camera upside down. I'm just used to it at this point lol, but I started doing it so that the AZ/ALT controls better correspond to how the object moves in the FOV. Up is up, down is down, etc

[livid sierra]

Huh, for me up is up when the camera is right side up in the focuser

Right side up as in, the upper half of the sensor is actually up

[somber stratus]

I think Jerry means to move Jupiter in the fov upwards, you press the up arrow on the HC

which is true if it's fippled south-up

[livid sierra]

Oooh that makes sense

Maybe I should try that too, think that could be a bit easier on the cable

Might take a little getting used to but for planets it shouldn’t be that bad

[somber stratus]

this is true

[steep apex]

Lucky perfect seeing conditions

For some reason the clouds only come at night

[thick heron]

My rotation is whatever happens to be the right orientation for the ADC to work with the camera threaded in.

[somber stratus]

I can't reach correction if I thread my camera. Ig too low of an altitude.

[fading plume]

You shouldn’t get a 3x Barlow. Get an astrocam.

[fading plume]

I’m not sure if it’s even possible to easily use an adc on an eq mount.

You’ll be struggling a lot. Having to rotate the tube etc.

[livid sierra]

More like having to rotate the adc right? Lots of people use adcs with eq mounts I don’t think they rotate the tube during imaging sessions

If that’s what you mean

[white prawn]

I kind of figured. I’m hoping that over the course of a single shot I won’t need to move the scope so much that I have to adjust the ADC. All I’m trying to do is get better images

[thick heron]

Easy. Just rotate the ADC, but you usually don’t need to do this over a typical imaging run on one target.

[livid sierra]

Yeah no need to rotate the tube

The hardest part will be finding out how your adc should be oriented in the focuser

[white prawn]

Thin side goes in, yeah? 😁

[livid sierra]

That’s a good start but I was talking about its rotation in the focuser not which side goes in first

[thick heron]

Levers should be parallel to the ground in their neutral point.

[white prawn]

I kind of figured that and I was getting a feel that what @thick heron said was the case, and I'm sure I'll have a healthy appreciation for it when I see it. That all being said, I had an opportunity for an easy wiseguy comment that if it dug at anyone it was me, so I took it.

[steep apex]

Sunday looks like it has good seeing!!!

And hopefully today too

[fading plume]

Going for the Venus inferior conjunction?

I’m doing that today and tomorrow

[coarse aspen]

how close will venus be to the sun

[fading plume]

7 degrees

[steep apex]

No, I’m too scared to do that, just looking for good seeing in general to just do some planetary imaging

[coarse aspen]

close

not that bad

[fading plume]

Scared? Just sit behind a building

[coarse aspen]

didnt venus transit the sun last time orr

[steep apex]

I’m gonna try look for one

[fading plume]

Yeah barely out of naked eye range I find

[coarse aspen]

im not trying to look that close to the sun

[fading plume]

It’s fine. Just squint a bit.

[coarse aspen]

what about sunglasses

would that help see venus when its that close

[fading plume]

Sure. But you probably just want to use binoculars

[coarse aspen]

hell no

[fading plume]

Why

[coarse aspen]

wh-why??

[fading plume]

The sky isn’t that bright at 7 degrees

[coarse aspen]

THATS NOT THE POINT 💀

[fading plume]

I can use my dob to do visual with no problems

[coarse aspen]

EVEN WORSE

[fading plume]

What why

Lmao

[coarse aspen]

You're pointing a telescope close to the sun. One misinput

[fading plume]

Who does daytime observing with access to the sun???

That’s just stupid

You sit in the shade. Otherwise your telescope gets hot or you loose contrast.

[coarse aspen]

You have way too much trust in that building or whatever blocks the sun

What if the building disappears

[hasty hull]

if it’s in the shade, then it cant see the sun which is the point lol

[fading plume]

Yeah no one is stupid enough to put their telescope in direct sunlight.

[hasty hull]

oh hello there

[proud mulch]

What is causing this bow shock 🤢

[white prawn]

You really going to underestimate that?

[fading plume]

I hope not

[uncut glade]

Could be collimation, or focus. If your collimation screws are super tight around the mirror you could have an induced astigmatism

Safe bet would be redo collimation and make sure you don’t pull too hard, and focus on Jupiter’s moons to check focus isn’t weird

If focusing produces a hyperbola just before central focus, it’s collimation

[livid sierra]

k

[fading plume]

I’m actually gonna flip. Cloudy as soon as I set up. Been like this all day. Now Venus is too low.

[heavy mirage]

You were right, tonight is also very good maybe even a bit better than yesterday

This is 34 degrees

[winter heath]

Hi everyone, just looking for advice as to how I can get a clearer photo of Saturn? I’ve stacked roughly 600 frames in Pipp last night and ended up with this after tuning on registax, but still not too happy with it - it’s my first photo I’ve taken and I’m sure I’ll get better, but wanting any advice on how to do so. Kit: 10 inch dob, manual, canon 4000d DSLR, 2x Barlow via 6mm plossl lens

[cursive inlet]

😊

[somber stratus]

great to hear i'm not hallucinating 😆

[heavy mirage]

The transparency is a bit worse than yesterday but better seeing kinda makes up for it

[steep apex]

[proud mulch]

Did you buy UV IR CUT

[steep apex]

No but might be today

[hasty hull]

what cam are you using

[steep apex]

Neptune-C II

[hasty hull]

oh nice

[somber stratus]

You definitely need an IR cut then

[vapid depot]

what's my best option for occasional planetary with a c6 sct and 2x barlow? currently use a 120mc-s but i get weird hot pixels in highspeed/turbo mode that wont go away because of good tracking. its just old, not sensitive, and yeah. time for upgrade

662 doesnt look bad at all but not looking to NIR image or anything like that atm

[thick lotus]

If you do not mind unnecessarily big sensor, 533 should not be half bad either

and it is actually nice if you do solar or lunar

[vapid depot]

i got much worse uh i forgot what the name is

ghost rings? on planets . the small aperture phenomenon

compared to the asi 120mc-s and yes i used a uv ir cut

[vapid depot]

too much to spend on a camera just for planetary tho but ty.

[thick lotus]

how about 662?

[vapid depot]

id be willing to get that yee, wanna sell the 120 anyways

[thick lotus]

I have been thinking going 662 if my 120mc-s and mm ever die or I get really good offer on them

But so far I have managed to see any feature that I want to see with 120mc-s, at the moment I think upgrade would just make them look better, if saturn was high enough to image I think the lesser dynamic range of 120 would start to show way more

some really subtle stuff on that one at times

585 mc also looks really enticing

[vapid depot]

do you have purple and yellow stuck pixels when turning on high speed mode /overclock?

i am getting worse imaged tracked vs untracked/ alt az tracking cuz of it

[thick lotus]

I have never been really happy with image with really high fps so I keep it more conservative

Bit lower framerate leads to way better images at least with my sample of 120mc-s

[coarse aspen]

theres always the 585

[thick lotus]

and 678

[vapid depot]

2 micron pixels an issue at f/20 150mm?

Looked at the 178/678 a little too

don’t think I need the extra sensor size tracking on an eq6 , but yeah smaller pixels than 290/585/662

I heard the 5x your pixel size is a good focal ratio to be at for planetary, I’m at f/20 and yeah 5x 3.75 is v close to that

[thick lotus]

only need F/10 with 678 really

[vapid depot]

Oh wow lol

[thick lotus]

it is the ideal camera for your celestron SCT folk that want ez solution without barlows etc for decent images I think

without much fuss

[vapid depot]

Alr I’ll look into it fs. But 662 still on my mind lol

[thick lotus]

small pixels usually make me wary but in modern cmos chips they seem to work fine

[vapid depot]

I still don’t like 183 deep sky data for some reason

But yeah this is planetary chat heh

I bet it’s a good planetary cam if someone has a 183mc/mm for dso’s already

[thick lotus]

I was also thinking that the 678 would actually make nice live view astronomy camera binned 2x for small targets like galaxies and planetary nebulae

[vapid depot]

Yeah for sure good eaa cam

I’ve seen a 178mm + 50mm lens video viewing dso’s in real time

pretty cool

[thick lotus]

Big part of what I do is that, was always visual person so it feels like closest pareller and super cool to be able to let others watch on screen

[vapid depot]

yeah I’d love to do it at a star party / dark site with a crowd

Best I could do was let people look at 180s subs lol

[fading plume]

Amazing seeing

[proud mulch]

This is probably the worst idea ever

[fading plume]

I’m in the shade. It’s all good

The sun can’t hit the mirror

[proud mulch]

Ok

[coarse aspen]

it almost can

dude the finder scope is illuminated

[fading plume]

I have paper on it

Only the top half of the lens is off axis illuminated. The light is focusing on the side well before the focal point

[uncut glade]

Braver than the marines tbh

[fading plume]

Closest approach, to the hour.

[uncut glade]

Pro tip to everyone out there, when going for an IR Uranus, don’t use a 850nm+ band pass filter. You will receive individual photons per pixel

[onyx garnet]

is that a pixel cluster or a star cluster

[somber stratus]

Use 16-bit mode, increase exposure, lower gain.

Wait is this Uranus, or the Uranus-C camera

Uranus has a sharp absorption band in 840nm+ due to CH4 so it's incredibly dim.

610, 685 are the ones to use for IR-RGB work

[uncut glade]

The planet Uranus lol

[uncut glade]

That makes sense, I’ll look into getting one of those filters now, explains a lot

[coarse aspen]

Is that even the "surface" illuminated

Is that just like, the atmosphere if you know what I mean

[fading plume]

Cutout

[tiny cove]

guys can someone help me editing this stacked image on autostakkert?

my registax skills are not the very best

[steep apex]

What’s your guys’s opinion on my processing?

[hearty fiber]

Tinge yellow

Looks p good other than that

[heavy mirage]

Do you use 16 bit mode for all your images? Do you have any comparison images?

[somber stratus]

No. It’s only really needed for dim objects or where you need dynamic range. It just ensures you’re not clipping some pixels to black.

Venus nightside, CH4 imaging, and Uranian ring attempts I use it

And Solar as this needs dynamic range for the prominence detail.

[heavy mirage]

@somber stratus nice, thanks for the tip!

[cursive inlet]

@somber stratus unrelated to planetary but would you use 16 bit for dob deepsky?

[somber stratus]

Yeah

[cursive inlet]

k

[random pecan]

processing is great, a tad over exposed though

[cursive inlet]

A tad bit too warm also I think, but maybe thats just my screen

[white prawn]

I don't think it's just your screen. Looks a bit orange/yellow

[cursive inlet]

I’m back bitches

[somber stratus]

That is one sun bleached finder scope

[cursive inlet]

Yeah, looks kinda nice tho

[livid sierra]

Ayyy

This is the 10” at your vacation home?

[cursive inlet]

Yessir

[livid sierra]

Good shit

Looking clear tonight? There’s a Tethys transit on Saturn

Starts around 22:00ut

[cursive inlet]

Eh kinda, i need to check if Saturn clears the trees by then

Ok yeah I think so, if not then I’ll try to move the scope back a bit

[livid sierra]

I might be able to catch a few minutes of it

Did some imaging last night, best seeing in like two months

https://media.discordapp.net/attachments/570687129118703637/1140425616227848252/2023-08-14_01-23-25.mov

https://media.discordapp.net/attachments/570687129118703637/1140461082469736469/2023-08-14_03-44-40.mov also Io transit on the GRS

[cursive inlet]

Kinda crazy that this transit will probably be my first real Saturn image, since I started serious astro in December when Saturn was blocked for me.

[livid sierra]

Wild

I saw Jupiter visually in proper astro dark through my 12” for the first time last night

That looked amazing too

[cursive inlet]

How much is seeing effected by a lake?

[livid sierra]

I think shooting over a lake is actually beneficial for planetary

Doesn’t release any heat like concrete or rooftops for example

[cursive inlet]

Cuz theres one like right next to me

[livid sierra]

Should be pretty good I’m sure

I can say for sure it won’t make your seeing any worse at least

Where’s your vacation house located?

[cursive inlet]

Really? I always hear Dylan O’donnell complaining about imaging in a coastal location

[livid sierra]

Might be that it influences the higher atmosphere more but I think that’s mostly around coastal locations like next to the sea

[cursive inlet]

Aight

[livid sierra]

And even there you can also get laminar flow which can make for excellent seeing

Tom got some really really good images at the Southern coast of England last year

Imaging right over the canal

[cursive inlet]

About 54.7 N

[livid sierra]

But it looks like you are shooting over a lake and a forest so you shouldn’t have to worry about turbulence because of ground heat rising up

All you might have to worry about is dew

Especially since you’re in the middle of a grassy field

I used my fan for dew last night lol

Worked pretty ok, had it on the lowest setting and did an alright job at keeping dew off my secondary

[somber stratus]

You also shooting it tonight?

It's actually my first shadow transit of the season, including Jupiter lol

Permanently get the non-GRS side with no moons.

[cursive inlet]

I’m gonna try

[somber stratus]

Will be difficult with an 8" but hopefully you get the seeing to support it.

or is that a 10

Can't tell.

[cursive inlet]

Summer house 10”, but the problem is I’ve had it so long I lost the secondary collimation hex driver, and the laser shows its a little out, not by a lot but it might be a problem.

[somber stratus]

Can't imagine it'd be too severe.

Secondaries don't move that much by accident.

[cursive inlet]

I loosened two of the extension bars to get the laser dot closer to the circle on the primary, dunno if thats a good idea or not

[livid sierra]

Mine moved a good bit when I dropped a plank on my scope and my focuser disengaged

[somber stratus]

lmao

[livid sierra]

Lol

[somber stratus]

It works, but it's scuffed.

[livid sierra]

You only loosened two of the trusses?

What does that do?

[somber stratus]

Rotates the OTA slightly. Moves the secondary a touch.

[livid sierra]

Ah

[cursive inlet]

I wonder, is collimation kind of like coma? What I mean by that is, coma is less of a problem at high magnifications, does collimation work the same or not?

[somber stratus]

Not really. It's about the same at all focal lengths from what i've seen.

[cursive inlet]

Pretty decent platform tracking at 3600mm

[somber stratus]

That's good that.

Dew destroyer v2 in action

[livid sierra]

Very nice

But barlow tf up bruv

[cursive inlet]

Idk i might attempt the ring nebula with the 3x in the coming days, given that im in bortle 2 with a 10”, it might work.

[somber stratus]

I've found you can only ever get away with a 2x

Sucker is bright for a DSO, but still incredibly dim at f/13

[somber stratus]

Tethys transit ingress in 20mins

Still super low for me though

[livid sierra]

Getting clouded over here lol

[cursive inlet]

Seeing in color is pretty meh at the moment, hoping it will get better over the next 2 hours.

I think the transit will def be doable with the 685nm though

[cursive inlet]

Perseids are crazy rn, seen like 10 so far

[livid sierra]

I saw a big one too earlier

[proud mulch]

Saw a big one when I got home

[livid sierra]

How was the Tethys transit friends

[proud mulch]

Cloudy and daytime

[blazing hazel]

damn that’s an amazing photo , great detail mate nice job !

[deep island]

thanks!

[green pebble]

I saw 2 really big ones and i couldnt count the rest of them

[high hull]

saturn taken at july 31 at 217 local time

sky and telescope prediction

riddle me this nerds, where has dione gone in my image, why is enceladus brighter than dione thats not how it works

and why does stellarium place enceladous half an orbit ahead, somebody is wrong in this

maybe the solar system is just engaging in a smideon of trolling

[blazing hazel]

no problem

[cursive inlet]

Jupiter and Calisto from last night, gonna process Saturn now and see if I got the Tethys transit or not.

[cursive inlet]

Yes or no?

Seems to match with Stellarium for me

[sharp ridge]

its just random noise to me

[cursive inlet]

idk maybe its just confirmation bias

Center of the video

[steep apex]

How do I fix low ram storage when I’m capturing a video

[cursive inlet]

get more ram

[sharp ridge]

download some ram™️

seriously tho, uh use a external ssd hard drive and use roi capture

[tiny cove]

Guys Zwo ASI120MC-S or Player one ceres c which one is better?

Is there any significant difference?

[livid sierra]

Ceres-C would be better but if budget allows I'd try to get a different cam

[tiny cove]

No unfortunately it is going to be my first cam so no, its already my max

[livid sierra]

What telescope do you have?

[tiny cove]

Umm astromaster 90 eq I know people dont like it but im okay with it

[cursive inlet]

Second night in a row

[tiny cove]

But i can understand them at some point

[livid sierra]

Yeah it's not the best scope, especially for planetary

[tiny cove]

But i think it can do something i mean its not the worst

Right? 🥺

[proud mulch]

Felt that :(

[white prawn]

What I want to know is where to get those lawn chairs that lean back all the way.

You have a doublet frac though which might fuc the colors up a bit

Still, I’d say you would still get something

[proud mulch]

Why is the grs so big

[steep apex]

It used to be that big

[cursive inlet]

Idk, aint my photo

[proud mulch]

But it isn’t now

[steep apex]

The GRS is shrinking

[hasty hull]

due to disappear within the next couple decades pretty sure

[steep apex]

I wonder how large the GRS was at its max size

[tiny cove]

Oh ok thanks for that

[uncut glade]

At least this large

Based on this imagery ^^
Damian Peach records from his own data a shrinkage at a rate of 250km per year

Excellent article

[vapid depot]

One of my old planetary shots from 2019 and my c5 sct and 120mc.. is it even possible to get the Saturn hexagon w 5” sct or am I trippin lol

I thought I did but wasn’t completely sure

[proud mulch]

It may have been bigger tho

[proud mulch]

I see the hexagon

Looks hexagonal

[vapid depot]

yeah im just not sure if its actually in the data or some sharpening artifact

considering the instrument size and focal length of around 2500mm lol

good seeing but still.

[proud mulch]

If it looks hexagonal it’s a hexagon

Plus you got the front Cassini division so the hexagon should be ez

[vapid depot]

eh cass div is easy

ive seen it in 80mm scopes

7 inch apo view on planet must be cray

[proud mulch]

Front Cassini is harder tho

[steep apex]

What kind of storm on Saturn is this?

[proud mulch]

Great white spot :DDDD

I caught it I think

See that white smudge

[steep apex]

I thought the great white spot was more between the central band and the poles, not at the central band

[proud mulch]

Idk man

[steep apex]

Very good 10/10 seeing

[proud mulch]

Don’t use auto align and also use cutout please

[steep apex]

Yeah I’ve been planning to change that

[proud mulch]

DO IT NOW

NOW

[steep apex]

Guess I just need to turn off the ground

[proud mulch]

NOW I SAY NOW

[proud mulch]

Huh

[cursive inlet]

Gonna try Neptune for the first time

[livid sierra]

Good luck

[uncut glade]

4x3min videos derotated in average seeing, getting these weird color granulations across the surface in almost a bayer(?) pattern when you zoom in. They're slaughtering the detail, anyone know what they are?
C11, Uranus-C with 3x Ultima barlow, no ADC

[white prawn]

How long are you guys imaging Saturn that you need to derotate? Like, I'll do a 3 min image of any planet so I don't have to muss w/ derotation

I suppose another question is how long can you image and use the fact that you have to derotate, to make a really cool beans rotation video?

[cursive inlet]

Pretty glad I got Triton at least

[livid sierra]

Not bad

[cursive inlet]

Worth going for Mercury in 850nm in daylight?

[eternal solstice]

imagen if at one point it was the size of the whole planet

[sharp ridge]

a year ago, cuz nowadays my goto is bad and i can only image it when i leave home

[cursive inlet]

Bruh these bugs are having sex on my dob wtf

[livid sierra]

Lmao

[hearty fiber]

Don't post bug porn, there are children here

[eternal solstice]

"mommy, what are those two bugs doing?" mommy:" well, son, it is time you should learn about the birds and the bees"

[hasty hull]

It’s pretty much at aphelion right now, will be extremely difficult to find

[cursive inlet]

Yeah thought so, spent an hour looking for it couldn’t find anything

[hasty hull]

Sept 22’s western elongation is basically at perihelion so that will be a really good chance to find it

[cursive inlet]

Last planet on the list for me, pretty excited

[random pecan]

Very happy with the results!

i got 40-50 minutes worth of rotation im processing now

but autostakkert does not do bath processing well

[livid sierra]

I'm still trying to process my Neptune data from the 14th to get it to look good. If I finish it it'll have been my last planet to capture

[random pecan]

does neptune have any surface details with telescopes 10"> of aperture

or uranus, ive never imaged or attempted those planets

[cursive inlet]

The only Neptune images with surface detail I've seen were from Damian Peach and Tom, both have huge scopes, way bigger than 10"

[cursive inlet]

Uranus has a polar cap in near infrared which is pretty easy to capture, I've done it with my 8"

[random pecan]

Woajhhh

[cursive inlet]

This was IRRGB, color and IR image combined into one. IR was at 685nm

[white prawn]

That can't be from an 8" scope

[livid sierra]

@cursive inlet I processed mine #older_system_pics message

Now I can quit ap

[cursive inlet]

goodbye then

[cursive inlet]

I wonder if that bright spot is actually something or just noise

[livid sierra]

I’m not sure tbh

Optimistically it’s detail, realistically it’s noise

[cursive inlet]

kinda reminds me of toms image a while back

[livid sierra]

Yeah I agree, similar bright spot and similar greenish noise

[somber stratus]

If it shows up in most stacks then probs detail

otherwise process softer and it'll be more obvious despite being blurrier

[white prawn]

Guess who has two thumbs, cloudy skies for the foreseeable future, and got his ADC in the mail today

Same guy who doesn't know how to use it

[livid sierra]

I’ll scroll through the stacks soon see if it’s there

[random pecan]

Ah I have a zwo 950mm

I need a 685mm

That’s awesome though I will try it

I’ll have to get the 685nm especially with how much people talk it up

Nm not mm whoops

What’s a good brand

Just baader?

[cursive inlet]

Definitely worth it, its my most often used filter apart from the ir/uv cut ofcourse. Its good for basically any target when the seeing is bad.

[random pecan]

Good

[cursive inlet]

They are all the same

[random pecan]

I’ll nab one

Oh?

[cursive inlet]

it all comes from china anyway

[random pecan]

True

The antlia one is 30 dollars

[cursive inlet]

I have an Antlia bcs it was the cheapest one for me

Also it doesn't matter at all, but Antlia packaging is very nice, the filter comes in a cool magnetic case

Very satisfying to open and close

[livid sierra]

Woah that’s very cool

[livid sierra]

@somber stratus @cursive inlet I scrolled through the stacks and while it might be confirmation bias I do feel like it shows up in a few stacks

Not each stack but it's also hard to say for sure since Neptune is only like 28px wide

It's somewhat distinguishable in ~7 out of 14 stacks

[hasty hull]

woah that’s rad

[uncut glade]

Is the 5x your pixel size for your f ratio thing a good rule to follow for arcsec/px or is that a generalized thing for seeing

[low tendon]

Jupiter

[cursive inlet]

Its a rule of thumb on how to pair different scopes, barlows and cameras together.

[steep apex]

Dude there’s this tropical storm near me and it just decided to break apart and change trajectory to my location

[green pebble]

[mental void]

[past ore]

saturn from last night- 6 inch dob, canon 100d (I think, its called a rebel sl1 in canada) processed with pipp, autostakkert and registax. Im not very good at planetary but its a lot better than my first image from last year.

also i dont know why tha weird gradient line thing is there so just ignore it lmao

[hasty hull]

Lookin good man nice job

[past ore]

Thanks man appreciate it

[past ore]

Damn bro okay I had no idea I could do that lmao I used the 5x view to focus but I didn’t know I could record with it going

[nova delta]

I never tried planetary with a DSLR, but how does that work? You’re changing live view zoom…?

What does that change then?

Doesn’t make sense in my head

Does it crop the video or what?

Oh ok

Still doesn’t really make any sense to me

Ahh now I get it

Thanks

[uncut glade]

Just now realizing how big of a difference 2/5 vs 3/5 seeing is. The details are double what I've had before.

Like man, living in a valley really does just screw up seeing.

Need to go to New Mexico lol

[past ore]

Oh well I don’t have a laptop that I can do that with

It’s fine I use my dob for visual mostly and I just do a lil planetary from time to time

[sharp ridge]

[steep apex]

Where did red spot jr go

[proud mulch]

Gone

[steep apex]

I wish we had another 2017 Jupiter, great storms, great disturbances

[uncut glade]

“Man that’s weird, why is it clouding over for a week straight in the Utah desert?”

Found the culprit

[steep apex]

At least by the time it reaches Utah, it’ll be a tropical storm, then later a low pressure area, could be worse

[sharp ridge]

generally before a typhoon arrives there will be one or two nights of clear skies and crazy good seeing ...

also, someone should try imaging from inside the eye of the storm

[uncut glade]

Oh absolutely lol, just we NEVER get big storms this time of year. It’s weird. Hope LA folks are good

[blazing hazel]

did anyone here take a pic of a moon crater and it looked like u was standing on the moon next to the crater and took a pic of it ?

bc i know i saw it and i can’t find it and i need to see it

[topaz elk]

prolly either ken or tom’s picture

[uncut glade]

#older_system_pics message

Could be that image, feels like a normal landscape shot

[somber stratus]

This one is also similar perhaps.

[steep apex]

Could be Pythagoras crater

[blazing hazel]

it was like a picture of a single crater

and it looked like he was standing on the moons surface and took it

[fading plume]

Tethys, Dione and Rhea
