Planetary Imaging

[obtuse yew]

My 10 inch is untracked, and for this reason I've always used short exposure times like 5-10ms. I'm not sure if this is really necessary

[somber stratus]

It's tracked, SW Synscan GoTo

[somber stratus]

probably, you have drift to deal with

i use 10-15ms tracked due to seeing anyway

[obtuse yew]

Very good to know. Thanks for the advice Tom, your images are hugely inspirational to me

I have one last question, for the 2023 planetary season, I have the option of either a tracked 12 inch, or an untracked 16 inch. If those were your two options which would you go for? I really do hate dealing with drift but aperture is king

[weary jungle]

When doing my planetary I have just been adjusting both gain and exposure till it looks all right is this the best way to do it. Or is there the right exposure time to use with different seeing?

[somber stratus]

Comes with experience, but i wouldn't go longer than 20ms in any case

then whatever gain is required to get good image brightness

[somber stratus]

hmm, idk, 12 probably unless seeing is supremely good

[thorn ledge]

What does look better?

seeing was nearly the same

[somber stratus]

what is a bresser wifi 3000

and left is better

but only bc of the colour is nicer

[peak lance]

That was how the math worked out to not smear even a single pixel, technically its the part facing dead on to you at the equator that smears first, then expands kind of in a circle from that point as you smear more

I'll see if I can work out how to visualise that

[somber stratus]

yeah i know, it's just AS!3 is great at correcting for the movement between frames

so these estimates are very conservative

[peak lance]

As ill have cloud for a while, possible to see where it breaks down? I'll update it to show where it should smear, most of its just going to be trig and drawing an oval over an image as the surface wind velocity ends up negligible

[somber stratus]

had a play with false colour & inverted images bc i was bored. This is just rad lol

[swift marten]

Could I get some quick tips for my first night doing astrophotography? I have a tripod and a DSLR, manually tracked, and I'm hoping to focus on Jupiter and the Moon for tonight

[topaz elk]

I was in your shoes once, I would use video if you have 1:1 crop and no compression for the video file. If not then RAW images would be the second best option. Make sure to use a fast exposure speed so the image and details doesn’t blur/smear. Make sure to not be touching your camera and let it drift across. Also, an intervalometer is great for the second option

[swift marten]

ill check the video capabilities of it but im pretty sure it can do those things

also, i can control exposure time from the camera itself, does the intervalometer do something else that would make it worth it?

also, thank you for the quick response

[topaz elk]

For the second option it takes images for you without having to touch it, quick and won’t smear your image

[swift marten]

ah yeah thatd be nice

[topaz elk]

More images is better so you don’t want delays in between

[swift marten]

how easy is it to smear?

[topaz elk]

It depends on the focal length and barlow but it’s not that easy for smear

i’d go somewhere 1/320 for exposure time

[swift marten]

oh im not using a telescope

i dont have the adapters required to attach it to my dob yet

[topaz elk]

Oh yeah I see

what’s the focal length in the lens?

[swift marten]

ive got a couple lenses, one is zoom

getting specifics now

[swift marten]

75-300, 24-105, 50, 100

all mm

[topaz elk]

ahh okay

i guess i would use the max focal length 300mm

you should be able to frame the full moon on that

for jupiter you may be able to get the moons but i don’t think you’ll get any details

[hasty hull]

Yeah moons of Jupiter will be easy

[swift marten]

will details of Jupiter itself be possible?

[topaz elk]

nope

you can try but i don’t think so

[swift marten]

will it be an issue of magnification or ISO?

cuz in that case ill only spend a little time on Jupiter and the rest on the Moon

[topaz elk]

magnification

[swift marten]

got it

thanks for all your help!

[hasty hull]

I’ve seen people capture Saturn’s rings at 300mm

[ebon sage]

I’ve seen it at 55mm

[fading plume]

X to doubt.

[topaz elk]

yeahhh no

not physically possible lol

physics is a thing

[topaz elk]

right but saturns ring are big

jupiter details are tiny

maybe possible would good conditions but highly unlikely

[ebon sage]

Someone’s done it in dis server

[topaz elk]

only one i found was a guy with a 300mm lens and and 2x

[topaz elk]

can i see?

you talking about kerbal madness?

[ebon sage]

It cropped

[ebon sage]

I think so

[topaz elk]

he has 1000mm lens no?

[ebon sage]

Post says 55mm fl for fun

[topaz elk]

rings sure but eh

[coarse aspen]

Fine, I'll do it myself

I will image Jupiter'

Jupiter's details with a DSLR and a Lens

No telescope because thats cheating

[topaz elk]

i mean a lens is technically a telescope

[coarse aspen]

Yeah but the camera needs a lens

so

it doesnt count

[topaz elk]

jupiter detail with 2.5 mm focal length

[coarse aspen]

literally impossible

[peak lance]

a telescope is just a bigger lens, its not really all that different

[coarse aspen]

i mean you're not wrong

but

[peak lance]

a manual focus, fixed focal length lens

[coarse aspen]

U know what I mean

It's not as powerful as a telescope

It's a camera

The goal is catch Jupiter's details with a camera

without a dedicated telescope

[peak lance]

no.. a 300mm lens made well enough isnt any real different from a 300mm refractor?

[coarse aspen]

stop breaking my argument

[peak lance]

I got into astro because I wanted a high focal length lens for daytime stuff and a telescope was cheaper... 😄

[coarse aspen]

i mean

a refractor is just a big camera lens

[peak lance]

reflectors too 😄

[coarse aspen]

i have never seen a reflector camera lens

not denying they exist just never seen one

[ebon sage]

thats so cute

[peak lance]

syms pocket sized rig using one 😄

[coarse aspen]

thats just monoculars

[topaz elk]

monocular is a telescope

[fading plume]

camera lens

[coarse aspen]

im getting destroyed here

I'm trying to make a point and I'm getting shot down immediately

someone help me out here

[fading plume]

@ebon sage

[ebon sage]

?

[fading plume]

look at the gif...

[ebon sage]

seconds ?

[fading plume]

yes. as3 can derotate a lot of stuff

40s isnt by any means the "limit"

or 2 mins

especially on your small scope

[coarse aspen]

so as3 is actually really good at derotation? damn i didnt need to derotate my 3x1min vids

[fading plume]

probably not yeah

[coarse aspen]

i didnt see any blurring in that gif

the quality only seemed to increase

[topaz elk]

well the limit is 3 mins so no

it’s more like past 5 mins is where ppl derotate

[obtuse yew]

Do you guys use brute force alignment or ultra smooth map recombination in autostakkert 3?

[topaz elk]

what?

[sharp ridge]

we don't

[barren dune]

Im basically starting from scrath with collimation with some cool new tools ordered a spotting template from catseye to makesure everything is centered and a book about newtonian collimation frpm the master of collimation vic menard and a 2in to m42 thread adpter to elimate and wobble when fine tuning with ocal. Ive now spent kore on collimation then I did on the scope my goodness it hurts. I hope I can be properly collimated by mars opposition if not then by jupiter szn next year 🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲🥲

My best Jupiter so far, shot with my iPhone camera and an 8” dob

I’m quite proud that I’ve got to the point where it’s not a glowing ball but now I lost the moons lol

[jolly ice]

@ruby tartan how much should i stack?

[ruby tartan]

I always stack 25% of frames

[jolly ice]

and how many APs ?
(this was taken thru phone and 8" dob)

[ruby tartan]

Depends on the size of the planet and the amount of detail, I usually put it in the equatorial bands and poles for Jupiter

[jolly ice]

is this fine then?

[ruby tartan]

I think it's a lot, usually mine has this amount of APs

I usually do it like this

[weary jungle]

Do you guys know when using a Barlow with my C14 that the quality of the images goes down then without? @sharp ridge

[ruby tartan]

2022-05-31

[jolly ice]

alr thanks

[jolly ice]

DUDE

[jolly ice]

the best image of mars ive ever seen till now

GAH DAYUM

[ruby tartan]

It is from the HOPE probe of the arab emirates, I only processed

[jolly ice]

oh

i have some Jupiter's data
if anyone wants to process , please give it a go :)

why cant i upload the tif

[topaz elk]

managed to get olympus mons

i have so mch to process and i wanna go to sleep

[hasty hull]

Good stuff

[jolly ice]

willaf

can you help me process jupiter

[hasty hull]

Possibly

Whatcha got

[jolly ice]

wait ill dm u

i cant upload the tif here

[ruby tartan]

Nice, do you use a 200mm too?

[topaz elk]

200mm ?

[hasty hull]

8”

[topaz elk]

yeah 8"

[jolly ice]

8" dob and ASI smth

[topaz elk]

mars is not fun untracked at 80 degrees

[hasty hull]

True

[jolly ice]

planets arent fun untracked , especially in barlow....

i mean we use barlow everytime

unless you got a 16" 💀

[ruby tartan]

80 degrees?

[topaz elk]

yeah 78*

[ruby tartan]

The maximum that Mars reaches here is 50 degrees

[topaz elk]

it was goddarn cold outside

[hasty hull]

That’s Jupiter for me, Mars reaches like 75 here

[topaz elk]

same

jupiter is like 50 and saturn is 40

[hasty hull]

Saturn is like 34 here

Can’t wait for later in the decade

[topaz elk]

focus is really hard when 80% of the frames are like this lol

[jolly ice]

saturn is smth like 70 here

[ruby tartan]

Another image from 2022-05-31 by Hope probe

[jolly ice]

can you provide the link for the data?

[ruby tartan]

https://sdc.emiratesmarsmission.ae/data/science?range_type=date&start=1653957333000&end=1653957333000&instrument_id=exi&latest=latest

[jolly ice]

ty

also can someone tell me how to edit the mineral moon?

[topaz elk]

saturation and vibrance

[jolly ice]

how

[topaz elk]

you just duplicate it

like u hit apply and do it again to boost it more

[jolly ice]

ahh

[jolly ice]

can you suggest any specific apps for this ? (free)

or softwares

@topaz elk bruh
if i upload the same image , the settings dont change LOL

[topaz elk]

@jolly ice darktable or gimp

[jolly ice]

alright

@topaz elk I tried 💀

[coarse aspen]

Noisy but good

[indigo oak]

sure that's not from your dob?

[somber stratus]

i would hope not

[ebon sage]

New best planetary images

[knotty salmon]

purely depends on the quality of the barlow

[somber stratus]

That just means you’re using a poor quality Barlow

What exotic said

[weary jungle]

Ok thanks I will look into a better one.

[indigo oak]

Just shot Saturn with a 20 inch scope, I’m hoping the data is nice when I download it later 👀

[fading plume]

10%

20%

35%

50%

[somber stratus]

Not even in 1% increments 🤏

smh

[fading plume]

smhmyhead

20% of my 3 min recording is my best saturn yet

i have a 5 min recording processing now, 9k frames

[sharp ridge]

yr sharpening wavelet is to big i think

[somber stratus]

i sometimes go as low as 8% & just stack the stacks / derotate

[fading plume]

i suck at em

[somber stratus]

maintains maximum image sharpness but enough data to denoise

[fading plume]

sweat

[somber stratus]

u got some weird debayer artefacting

[fading plume]

what stack is that?

[somber stratus]

20%

[sharp ridge]

denoise it out

[somber stratus]

you can

I literally go for max sharpness for the data. Slider 1, no denoise. Then use derotation to denoise through averaging

[fading plume]

alright, probably gonna reedit this later but this is the 20% 3 min

[fading plume]

runnin the 5 min through pipp before because as3 keeps failing with it. memory suff i think.

@sharp ridge what should my APs be looking like for a pipp stabilised video?

[normal forge]

@somber stratus may i ask you a question regarding a camera as you are one of the best planetary imagers here?

[somber stratus]

go ahead

[normal forge]

I already ask Ken but still, 2 statements are nice too.

I have a 6" SCT ( yeah kinda small but the way to go for me ) and if needed a 2x TelVue barlow.
Currently looking for a new camera to get the best results for lunar / planetary imaging.

The ZWO 432MM looks good when looking at ZWOs marketing BUT Ken already said that i would need insane FL to use it.

[somber stratus]

Ken is correct

[normal forge]

( I already had the 385MC, 178MM and MC, 294MC and 533MC for testing last years. )
I finally want to get a really good camera esp. for lunar imaging.

[somber stratus]

also i'd go for a one-shot-colour cam instead of Mono personally

hmm

ok, for Lunar mono can work of course

[normal forge]

That's what my 6" SCT can do with a 178MM under mediocre / meh seeing.

[somber stratus]

i'd say the Player-One Apollo-M Mini (IMX429) isn't a bad shout

otherwise the Player-One Mars-M (IMX290)

But tbh you're better off saving for a bigger aperture scope not gunna lie

Camera doesn't make that much of a difference

[normal forge]

I am sitting in the middle of 500k people. Seeing / transparency is an issue. So i am not sure if a bigger aperture would help.

[sharp ridge]

^^

aperture always wins

[normal forge]

Ok, you win here.

😄

[sharp ridge]

Tom in bad seeing > me in perfect seeing

[normal forge]

I mean, i saw your images here ( both of you ) - stunning!

[somber stratus]

Aperture really is everything

even in poor seeing

[normal forge]

The beautiful C9.25 jumped in price by 400€ here. 😦

[somber stratus]

Like under perfect seeing, Ken can barely resolve Ganymede's bright Tros Crater with a 11" SCT, but it's pretty much a certainty with my 16" Dob regardless of conditions. It's a joke.

[somber stratus]

inflation moment

[normal forge]

Ok ok ok. Wait what?!

I should add - big city, balcony is right now the only way to go. Sooo a dob is ehm... maybe not suitable.

[sharp ridge]

honestly dob works better there because polar aligning a eq on a balcony might be hard :). unless you get a cpc9.25

[somber stratus]

Yeah, no im not saying get a 16" Dob lol, i'm just emphasising that it's probably worth upgrading the scope rather than the camera

Also balcony can improve seeing quite drastically due to the height above ground which re-radiates heat

[normal forge]

I do polar alignment without seeing north at all ( balcony facing East - South - West only ) in 5 mins. No problem. 😄

[sharp ridge]

[normal forge]

I was hoping ZWO would release a successor of the 290.

[somber stratus]

yeah

mono version of the 462 would be cool

with IR sens

[sharp ridge]

662 now right?

[somber stratus]

yeah, or 585 tbh

585MM 🔥

[sharp ridge]

[somber stratus]

tbf they have the uncooled 533 at Player-One

that's close enough

91% QE, IR isn't as good though of course

[normal forge]

Tom, Ken... if you tell me now that those 2 cameras as nice and would fit my scope... i will actually buy / test them. 😄

[sharp ridge]

buy both 290 and 662 , use L-color method

[somber stratus]

462, 585 & 662 are OSC colour cams. The uncooled Saturn-M SQR (IMX533) is mono

Damian Peach now uses the Saturn-M with his C14

but it is near 1000 euro

OSC cams aren't

[normal forge]

O_O i saw it on their page

[somber stratus]

Also, aperture moment, to prove my point. Trash seeing but Ganymede's still insane. This is 1m scope

[normal forge]

A dobs would cost me another 1000 here.

A dobs adds even more questions. Flex-tube? Solid tube? Which aperture?

[hasty hull]

I can’t unsee this

[normal forge]

;D Oh come one. And for the lols - add the 432MM.

[sharp ridge]

well, only for solar

[normal forge]

Thank you guys for your help! 🙂

[ruby tartan]

The best planetary astrophotographer in the world

[normal forge]

@sharp ridge L-Color method?

Like using a Luminance filter?

[somber stratus]

guessing you've seen this one of his? (well, kinda shared credit). Pic Du Midi, France. 1.06m scope.

[sharp ridge]

use mono capture then color then mono, derotate them to same time and combine
this guy from japan does it very well https://www.youtube.com/user/SuperRbstar

[somber stratus]

i think it remains one of the best ground-based images ever taken, period

[hasty hull]

dude

[somber stratus]

you still lose SNR. I'm confused what he's doing

[hasty hull]

that crazy

[sharp ridge]

idk, although his color result is dog, his lum is great which saves the image

[somber stratus]

im confused, he uses two diff cams? OSC for colour layer & mono for Luminance with a UV/IR cut?

[ruby tartan]

Bro, I've seen all his pics, I'm fan number 1

[sharp ridge]

yeah, with flip mirror

[normal forge]

Well, i wanna stick to lunar first. Try to get some nice details close-ups. No full disc or stuff i posted earlier.
More like that image but better. ( YES, more aperture but for that i need to talk to my telescope dealer. )

[somber stratus]

interesting

i wonder why its better, ik improved SNR

but why would the sharpness be better, or is it not

[sharp ridge]

his imaging train looks fkking ridiculous

[somber stratus]

lol

tbf you may as well just go full mono, makes no sense

colour response on OSC cams are slightly overlapping due to the QE response.

So it's not as clean and/or accurate

Custom GRS settings for stellarium, accurate to ~7 years.

^are you able to pin? @sharp ridge

[sharp ridge]

well its easier, you just need a few mins of color data and focus all on mono lum

[sharp ridge]

nope :C

[somber stratus]

suppose

Well in which case, of course his OSC data will be trash looking

if he's only doing a few captures

[normal forge]

There is a successor of the 178MC?! The 678MC... mhm. Any thoughts on that?

[somber stratus]

havent looked at it

All i look for is FPS, QE Response (including IR), and then FOV/Pixel size

ah not that guy smh

[coarse aspen]

Aw hell nah not this fella

[ruby tartan]

What happened?

[somber stratus]

big funny

[somber stratus]

nothing, just stupid good

[ruby tartan]

I will ask the raw files for him

[normal forge]

OK guys. I will do it and report.

[somber stratus]

tbf i could also ask D Peach for the raw files from the Pic Du Midi observing mission

i've been in contact before

[normal forge]

Guess i am the first to test the 678MC here. OSC it is - as you said there is nothing wrong with lunar imaging with OSC.

[ruby tartan]

I don't think he will send it to you, he didn't even send these files on patreon

[somber stratus]

ah

he's probably not allowed

as it's shared

owned by the obsy probably

[coarse aspen]

He owes his images to the company store

[normal forge]

Ok ... ZWO 678 MC order done. Reporting back in a few days! ❤️ I have already someone who would take it if i don't need it.

[ruby tartan]

I was looking at his patreon and I found the pic du midi file

Dahm, I forgot how good his files are, I'll process it all over again

[fading plume]

Maybe done editing

Pretty good compared to my old one

[hasty hull]

Good stuff

[fading plume]

Slightly better than first one too.

[hasty hull]

Looks kinda like my first Saturn

[fossil schooner]

I’ve been using a dslr for planetary and I kinda want something a little better, is there something that would fit an f/5 12 inch dob well that might work for planetary and maybe dsos?

I would use my dslr for dsos but it can’t reach focus with anything below a 3x Barlow

And a camera that can do dsos and planetary may be a bit much to ask but something that won’t break the bank that’s good at planetary would be nice too

Also preferably a color camera because idk how to do mono stuff lol

[fading plume]

hi, a quick question whats better: plain sensor or crappy color abberating 2x barlow?

[fading plume]

[weary jungle]

@somber stratus I know you said it was probably just a low quality Barlow but do you think not using a UV/IR cut filter with the ASI462MC would make it more blurry?

[somber stratus]

You should always use a UV/IR cut

in any case, and it shouldn't affect image quality at all

in terms of sharpness/blur

[weary jungle]

Ok because I wasn’t using one at the time I had forgot to put it on because clouds were coming quick. Also I noticed with the UV/IR filter the colors were a lot of is that normal?

[somber stratus]

Aug 9th, double eclipse polar projection timelapse

[topaz elk]

how do you derotate mars, is there a tip or something besides manually setting the outline?

[somber stratus]

not really, you just have to do it manually

[obtuse yew]

If you guys had a single 4-5 minute capture of Jupiter or Saturn, do you think you'd get the best result by stacking the whole video at once, or splitting it into 4-5 parts, stacking those separately, and derotating the stacks?

[somber stratus]

whole thing if you're using a mid sized scope

AS!3 is pretty good at dealing with a little movement

[obtuse yew]

It's a 10 inch

[somber stratus]

Just record 3m captures & you'll be fine

to do the whole vid

[obtuse yew]

Got it. I'll chop my captures into the best 3 minutes of seeing and do a single stack. No need for derotation until I can start taking much more data

3 minutes is a good rule of thumb for Jupiter, Saturn, and Mars untracked?

[ruby tartan]

And do it 10 times

zero noise

[somber stratus]

agree

[somber stratus]

5 for Mars

[obtuse yew]

Just out of curiosity, do you actually get the best result derotating 10 3 minute captures? Wouldn't that be way over the 15 min limit for limb artifacts?

[ruby tartan]

Mars - 30min
Jupiter - 10min
Saturn - 20min
Uranus/Neptune - 30min
I think that's enough

[obtuse yew]

I was under the impression that when derotating, 4 stacks is normally enough to drastically improve the SNR

[sleek drum]

made my first tiny saturn with that ductape barlow assembly. Next time i should use a guide cam, 6D pixels are too big

[somber stratus]

it is true that you get diminishing returns as you stack more as SNR increase goes with the sqrt (time integrated).
I.e 8 mins will have 4 times the data as 2 mins, but only sqrt(4)=2x the SNR.
Equally, it would take another 4 fold increase in data to increase the SNR by another factor of 2. I.e going from 2m->8m has the same effect on the SNR as 8m->32m, but ofc you're having to add 24mins of data compared to just 6m to double the SNR. Hope this makes sense.

The initial derotation of images, say 4 that you mentioned has a much larger effect than if you just added another 4 on top to make 8 stacks integrated.

[obtuse yew]

There's so much that goes into planetary imaging man. It's been a hell of a ride learning this hobby in the last year. Appreciate the help

I love this coloring that Damian uses, but it's really hard to get the same

[fading plume]

lmao i thought that was comparing images from your scopes

[hasty hull]

i dont think this star is symmetrical, do i adjust primary or secondary mirror?

[fading plume]

primary i believe

[hasty hull]

ty

[coarse aspen]

bro spent hundreds of dollars on collimation just to revert back to the old methods 💀

[hasty hull]

lol i think you mean Atreus

@fading plume better or worse lol

I think its better

[coarse aspen]

oh sorry

[fading plume]

better, needs to go towards 7 o clock

[coarse aspen]

you two have similar pfps

[ruby tartan]

I adjusted the colors a little more, now I think it's almost the same

[coarse aspen]

now you're as good at processing as The Peach

[ruby tartan]

🥹

I think I'm ready to capture Mars again, just wait for the sky clear

[coarse aspen]

i want a 6ft dob

[ruby tartan]

And I a C14

Wait, 6ft?

[hasty hull]

@fading plume close?

[fading plume]

yeah thats quite good

[hasty hull]

tysm for help

[topaz elk]

saturn rn

no registax or astrosurface on this laptop so only as3 sharpen

[coarse aspen]

oh my lord

seeing?

[topaz elk]

average

[hasty hull]

Seeing kinda bad rn

[topaz elk]

waiting for jupiter to rise

it’s behind a tree lol

[coarse aspen]

its already like 30 degrees here

[hasty hull]

Is this a collimation issue? I feel like it’s worse than before lol

Or just bad seeing

[coarse aspen]

seeing probably

[hasty hull]

I hope so

[topaz elk]

looks like stacking?

[coarse aspen]

the star never lies as long as its centered

[hasty hull]

Hmm idk, it was like a 45s capture

[coarse aspen]

there are 2 things that will never lie to you, stars and collimation cap

[hasty hull]

The collimation cap lied to me

It’s off center

[coarse aspen]

a centered collimation cap will never lie

[hasty hull]

True

[topaz elk]

oh i posted it twice oops

[hasty hull]

Exciting stuff

[topaz elk]

managed to get MW despite the full moon

[coarse aspen]

impossible

i can only see like 2 stars right now

im b9 currently

[fading plume]

i can get MW with a full moon tho

[coarse aspen]

arent you bortle 1

you image in the middle of nowhere

[fading plume]

3

[topaz elk]

i’m b7

[coarse aspen]

im b6 but moons upgraded me to b9

[fading plume]

good for pipp stabilised vid?

[coarse aspen]

no too many aps

[topaz elk]

yeah that’s a lot

[fading plume]

like 15-20?

[coarse aspen]

id do like 10 personally but

[topaz elk]

yeah maybe try 150 size

[fading plume]

150 gives 11

[topaz elk]

hmm

a bit smaller

[coarse aspen]

i only use 1 ap but jupiter is pretty small in my images so you need a bit more

too many is bad though from experience

[fading plume]

136 size gives 16

[topaz elk]

jupiter really good seeing

[coarse aspen]

it looks weird

oh thats because of the laptop screen through your phone

[fading plume]

not too bad for first ever jupiter with the dob

[topaz elk]

ya

waiting for stack

@coarse aspen

3 min stax

[coarse aspen]

JESUS

[topaz elk]

stack

[coarse aspen]

IT'S SO GOOD

[fading plume]

wat

hac

south is down here yeah

[topaz elk]

if anyone wants to process while i cap

@coarse aspen

[coarse aspen]

uhhh i might sure

ill do one for the homie

quick process coming right up @topaz elk

and registax crashed lmao

speedrun process

world record processing under 30 seconds

@topaz elk

[topaz elk]

yeah thats pretty soft

[fading plume]

Edited mine

[topaz elk]

what scope and cam do y have?

[fading plume]

Saturn stacks have been dialled in so gotta re-edit

[fading plume]

8” dob and IMX290 webcam

[topaz elk]

damn must be a low fps

[fading plume]

30

[topaz elk]

with smallest roi

[fading plume]

FPS is fixed and roi is a bit weird with sharpcap

[topaz elk]

oh sharpcap

scary

[fading plume]

It supports the full resolution of the camera though

Best compatibility

[topaz elk]

yeah since u do ap

[coarse aspen]

I'm used to my data

DAMN yours can be pushed really far

Sharpened further

[topaz elk]

yeah it was like 11k frames

25%

[coarse aspen]

Planetary processing is really easy tbh

much easier compared to deep sky

[topaz elk]

true

we dont get to capture for half of the year tho

[coarse aspen]

deep sky gets to capture any day that isnt a full moon or gibbous moon

[fading plume]

Narrowband

[topaz elk]

cant you do narrowband during full moon, or is that just LP

[coarse aspen]

you're right

but still anything near the full moon cant be saved

[topaz elk]

bad seeing again

[wary siren]

Was sent here from #🤓-ask-a-nerd: "I want to upgrade my planetary camera in a few months. I currently have an asi120mc-s, thinking about the Player One Mars-c? Might want to go with the neptune tho because of the wider FOV, I hand track and usually just let the planets cross the FOV so the small sensor size of the asi120mc-s is a pain, and the Mars-C isn't too much bigger. Just wondering if I would get less detail because the sensor is bigger/zoomed out more"

[wary siren]

was bored and saw this, thats some real good data

what scope/camera?

[topaz elk]

8 inch untracked and asi178mc

[wary siren]

oh just saw ur description lol

nice I also have an 8" dob

how was seeing during this?

[topaz elk]

4/5

[wary siren]

nice

[topaz elk]

with 8" id say imx462 or imx178 @wary siren

[wary siren]

ah so probably the neptune?

[topaz elk]

yeah if same sensor

i have the asi version

[wary siren]

oh ok

the neptune has the imx178

it'll be nicer too with a bigger FOV so I'm not shifting the scope every 5 seconds

[topaz elk]

its around 25 seconds for jupiter to cross at 2x

i get aroiund 3.3k frames

[wary siren]

oh ok

I usually use 3x

although I've tried 2x recently and it wasn't that much worse

[topaz elk]

yeah only 1.5x difference

[wary siren]

wait nvm 2x is probably optimal for your camera bc of the higher resolution

[topaz elk]

yeah 2x is optimal

3x isnt that much oversampling tho

[wary siren]

my camera is 1280x960 so I think 3x is optimal for it

at 2x I think its undersampled a bit

def undersampled at 2x for Mars, Jupiter and Saturn tho are still decent at 2x

[topaz elk]

asi178mc is f/12

asi462mc is i think f/18?

nvm f/15

[fading plume]

Nice. I have to basically track the whole time

Can’t wait for the dob motor mount thing to be done

[topaz elk]

yeah manually tracking is a pain in the ass

[fading plume]

Then you bump it and spend a full minute trying to find it again

[topaz elk]

really exhausting

yaeh lol

[fading plume]

I get about 4 1/2 mins of recording but pipp only outputs like 3 1/2 because it’s out of the frame most of the time

Not most of the time but yk

I’m gonna run some stacks of this data and blink it. This is so dumb I can’t tell the difference between it lol

liek

i think 50% which is what i edited before is best

gonna try my 50% drizzled one now

ok drizzled is def better cassini

vs undrizzled

both same preset for wavelets

[topaz elk]

1.5?

[fading plume]

yeah

[topaz elk]

looks better

are u undersampling

[fading plume]

i believe so yeah

2.9 um 3.5x barlow

F/21 or sumn

[topaz elk]

wait so ur oversampling no?

[fading plume]

ken reckons 7-10 x pixel size

[topaz elk]

damn

[fading plume]

im at 7 x pixel size now

[hasty hull]

Uranus tonight

[fading plume]

very nice

[hasty hull]

I feel like one side looks brighter

Possible polar region but idk

[fading plume]

check stellarium? or not recent enough if it changes

hmmm?

dada

cant find a wavelet which only touches the cassini details. Maybe i'll mask a ring in PS and darken it a touch

[turbid shore]

Why does your Saturn look desaturated

[fading plume]

i think its because my camera driver decided to set the gain to max, so i used shorter exposures because im a numpty so dropped dynamic range.

[turbid shore]

Was autogain on if you were using fc

[fading plume]

nah sharpcap, its just the slider displays the wrong value sometimes

if i click it it fixes it. I forgot about the issue because i havent done planetary in a little while

[turbid shore]

I’ve never had that problem with FC

Try FC for planetary

It works

[fading plume]

FC doenst like my cameras drivers much. It limits me to 480P downscaled.

SC lets me use the full 1080p

[turbid shore]

Oh

[fading plume]

my camera is like $30 so im not complaning

[turbid shore]

Buy asi 224mc

Best planetary camera imo

[fading plume]

nah, gonna get a 585 i think. I want something for wider FOV LI

[turbid shore]

Fair

[fading plume]

best value maybe, but 585 is pretty close in value too, maybe better

actually my camera is best value

[turbid shore]

Yeah true

It works so its best value

[fading plume]

gets pics sorta close to the 224, but not worth the extra $200 or so.

[turbid shore]

That is fair

[fading plume]

only complaints is the compressed output and basic drivers

alright i think i like this one

fuzzy in the right areas and sharp in the right ones

i lied

lied again, i hate wavelets

[turbid shore]

Making wavelets is annoying

[fading plume]

fr

[topaz elk]

i just use defualt wavelets

way easier

one single frame

really good seeing

no processing i just took a random single frame

[polar sequoia]

you can probably compare it to your images and figure out how close it was to mars on each day

assuming your view was from an infinite point

winjupos can def help

[molten kettle]

and JWST sees it in infrared

[ebon sage]

that was random

[molten kettle]

Bro what

[fading plume]

pretty excited for tonight

[knotty salmon]

yeah I was gonna say, seeing is shite tonight

[peak lance]

If its not a fast scope the secondary feels a bit weird. But primary is fine

[fading plume]

joobider, first time getting GRS.

only 2 1/2 mins with 25% stack. manual tracking sucks. Gonna go for more when its a bit higher.

@knotty salmon touched in PS.

[knotty salmon]

nice

got the stack file?

[fading plume]

25%

[knotty salmon]

where drizzle

[fading plume]

still working on other data, in a hurry BC GRS going in an hour

[knotty salmon]

@fading plume u gonna derotate?

[fading plume]

no

[knotty salmon]

lmc

help

look what ryan did to me

my name and pfp

[sharp ridge]

[ruby tartan]

My processing

Damian

[topaz elk]

looks like bad seeing ngl

[fading plume]

1/5 supposedly. was like 3/5 by my standards

[topaz elk]

either bad seeing or u don’t have enough frames

probably both

[fading plume]

that too yeah

only like 25% of 6k frames

[fading plume]

ngl i like yours more. better contrast and that red ring is gone

[ruby tartan]

Thanks

[fading plume]

this ones nice, i though it was gonna be crap

photoshopped

[plush sonnet]

plain sensor ofc

[topaz elk]

Petavius

[limpid reef]

very nice

[topaz elk]

do you check optimize image measurements for winjupos?

woah what happened ot my moon

[polar sequoia]

i guess im b9 but moon and artificial direct light sources upgraded me to bortle 15

[topaz elk]

new yorkans when they cant see jupiter when moon is out

quality graph 😩😩🥵

[hasty hull]

funny uranus occultation is tonight btw

just a reminder

[barren dune]

Yeah im plannjng something swank

[ruby tartan]

Good luck, here the moon will be a little far from Uranus

[barren dune]

My graph is better 😎😎

Only in texas folks

[ruby tartan]

Next occultation will be in 2023 for me

[barren dune]

@ruby tartan no barlow no problem

Lol idk tho it is pretty far

[ruby tartan]

About 2 full moons

[barren dune]

Not for me

Im down south

[ruby tartan]

Which country and which latitude? I'm in Brazil -10° from the equator

[barren dune]

😎

Us and i live in texas

[ruby tartan]

This I could register without barlow

[barren dune]

Yeah I think i can too

[hasty hull]

Yeah it’s similar for me too in Pennsylvania

[barren dune]

Thats its closest i believe

[sleek drum]

since the moon is out there tried to do some planetary for fun. Right is Saturn with my main canon 6D + 2x barlow, and the left one is using my guide camera (120 MM) without a barlow.

[fading plume]

How tf do I get precise focus on Jupiter. I can turn my focuser a lonnng way and the focus changes but not enough for me to see a difference live. Maybe it will be better when motorised mount and focuser is made.

[ebon sage]

I focus till I see bands then wait on that focus for a bit in good seeing to see and slowly tweak till I get what I think is perfect

[peak lance]

I use hocus focus on contrast detect mode and let my autofocuser deal with it 😄

[sharp ridge]

I rack the focuser back and forth until its very sharp, have to do it multiple times until seeing lines up

[ruby tartan]

Use the planet's moons to help focus, make them as small as possible focusing, I think this is the best method

[somber stratus]

Yeah, shadows on Jupiter can also be a good one

But that’s not always possible of course

[fading plume]

sweeeet

[normal forge]

All you need is a Tri-Bathinov mask. 🙂

[coarse aspen]

Does anyone here plan on imaging the New Moon occultation of Venus?

[topaz elk]

prolly not considering how close it is to the sun

iirc

[ebon sage]

I’ve never seen a moon shadow before I rlly want one in my image :v

[somber stratus]

Too close to the sun

[coarse aspen]

Not possible to image?

[somber stratus]

No, for obvious reasons

[ebon sage]

mirror dosent need to be ded

[hasty hull]

Elongation

[coarse aspen]

damn

[hasty hull]

This is what, like 2°?

[coarse aspen]

maybe a gigachad is gonna pull it off anyway

[somber stratus]

No

It’s just not really possible. Pinhole method might work but the angular diameter is so small at 10 arcsec anyway

Don’t think it could resolve it

[coarse aspen]

Thinking about this gives me an idea, earth-glow image of a total solar eclipse

Nvm its already been done

do double moon transits on Jupiter happen? Like 2 or more moons in transit at the same time

[hasty hull]

Yup, I’ve seen one this season

In august

Not the best pic but they are super cool

[coarse aspen]

woww

would be cool to see all 4at once

i think thats possible just rare

[hasty hull]

Yeah that’d be insane

[peak lance]

Row saturation at a glance,

[normal forge]

@sharp ridge The ZWO 678MC arrived today. A nice person helped me with spot-on collimation of my 6" SCT. Please don't mind the dust bunny.

Turned out, with the new camera, there came a TON of clouds for next days.
I was able to take 2 videos of jupiter through a thin haze of clouds and only the brightest stars where visible at all.
Seeing 1/5 - others here would rate 1/10. 😄

Under same conditions i went for moon and took a 2-3 videos. All of them inbetween clouds and still through the hazy whatever it was.

[sharp ridge]

nice, but make sure to use a closer focus (smaller circle) again to check

[peak lance]

Also its shape should not change if you defocus the other direction

[normal forge]

I have never seen a perfect 100% same inside / outside defocused airy disc on a SCT. 😄

Not in how-to videos, not in images that claim to be inside and outside def.

In the end i checked with Tri-Bathinov mask and it was spot on.

[topaz elk]

does the star method check for secondary or primary collimation?

[coarse aspen]

I think only primary but I may be wrong

[long kraken]

what is this and how do i kill it

[long kraken]

ok well i killed it now as is broken

[peak lance]

Primary for the rings, secondary gets hinted at by the shape but cant be used to correct

[sharp ridge]

Use the crop function to make the sizes the same

U can use same capture size it would just make black space

[long kraken]

also AS is having issues, part of me thinks its bad data, part of me thinks i don't know how to run as lol

[sharp ridge]

convert it to avi or ser file in pipp

[normal forge]

So if one direction is 100% perfect, but the other is a tad off -> how to deal with that?
Correcting the not perfect direction to nearly perfect results in not perfect anymore in the other direction. I can not get both 100% spot on now.

[peak lance]

you split the difference 🙂

[normal forge]

I do what? ( Sorry, not native english speaker. )

Like from 100% / 90% to 95% / 95% on the inside / outside defocus?

Tbh - my Celestron SCT is a trash can. It has so many issues, i am close to buying a new SCT ( 8" or 9.25" ).

[plush sonnet]

why is it trash though? Normal Cx series or orange tube or 1945 SCT?

[peak lance]

basically get it close so its even-ish on both sides of focus

[somber stratus]

Aug 9th

And you can’t get 4 of them due to orbital resonance between the inner 3. You can get 3 on the near side & the remaining one behind Jupiter & thus also nearby the planet though

[molten kettle]

just took some data of jupiter. Not sure if its my best but i tried

[normal forge]

Secondary mirror holder is getting looooooooose every now and then. Guess you know what that means - free rotation and a tad movement in the corrector plate. I screw it on again, collimate again. Sometimes it lasts 1 year, sometimes 2-3 months.
Next issue - the tiny screw in the secondary mirror that goes into the tiny notch of the secondary mirror holder is like 0.2-0.3 mm smaller than the notch. Result is a tiny bit of rotation of the secondary in the holder IF the fixation ring gets lose ( what sometimes happens too ).

It is just like the whole secondary mirror holder part is a mess.

[plush sonnet]

replace secondary and corrector plate then?

[normal forge]

If i remember correctly, Schmidt plate and primary are matched.
You can get a new corrector plate BUT it is extremly expensive and it has to be proper fitted to the specific scope. Sooo the time i lose by sending it to Celestron, the money i put into without unkown outcome in terms of quality after that ...

In the end i can buy a new C6 and fingers crossed hope for the best . 😄

[jolly ice]

shaking/shake my head my head

[fading plume]

Forgot when I asked

[hasty hull]

smh my head

[turbid shore]

Found Uranus for the first time, great right ?

Wrong. Turns out my telescope was knocked out of collimation

Awesome

[turbid shore]

Good news, fixed collimation to the best of my ability, and im now shooting mars.

I will buy a laser collimator for perfect collimating tomorrow

[ruby tartan]

Nice

[polar sequoia]

they dont really work that great from what ive

heard

if you have the tiniest error in the secondary its gonna do the exact opposite

[turbid shore]

Oh dear

How should I collimate then

[polar sequoia]

a cheshire

@knotty salmon is living proof of not using a laser collimator at any cost

[peak lance]

Or a collimation cap 🙂

[topaz elk]

would a $20 cheshire be good enough (average brands like agena or svbont) or should i buy a $42 cheshire from farpoint. scope is f/6 and f/12 with barlow

[peak lance]

you collimate without a barlow, the cheap one should be ok

[normal forge]

Depends on your Newtonian. There are so many ways.

• Laser ( if you get a good one that is perfect -> i bought a made in Germany, made on order with a CNC machine - its perfect )
• Cheshire ( if you know how to use it and don't missunderstand what you see -> make sure to pick the correct Cheshire, 1.25" or 2", short or long version! its important! )
• Concenter ( pretty amazing device! ❤️ )
• Collimation Cap ( i hate it, i wear glasses )
• Ocal Pro ( well uhm... depends on your focuser tbh. - mine s*cks and OCAL is useless )
• any centered webcam with a lense attached ( CCTV / ultrawideangle lense like on ZWO cameras ) -> Sharpcap to liveview and use their circle overlays to collimate

[coarse aspen]

Which version of cheshire? Short or long?

[normal forge]

Depends on your Newtonian. I have a supercheap f4 Newt with a huge secondary. The 1.25" Cheshire didn't work out well. In the end, i went for a Concenter. There was no way to get a 2" Cheshire cheap OR by import incl. high toll / tax on it.

If you have a astro retailer in your country, a bigger one that actually knows what they are selling - ask them!
I do that to.

[normal forge]

Or look for someone here that has a similar Newtonian.

[onyx garnet]

Jupiter and Saturn

[coarse aspen]

That Saturn has a lot of potential

For a single picture, you can see the band and divsion

Try taking a video and stacking, you will get way better results

[onyx garnet]

There's another one

Titan, Dione, Rhea, Enceladus, some random star

[coarse aspen]

Please do this

Do NOT underestimate the result of stacking

[onyx garnet]

When I get my cassegrain and dob I will

[coarse aspen]

Like atleast 10x more detail

[coarse aspen]

What did u take that with

[onyx garnet]

^

[coarse aspen]

This is an understatement tbh

[onyx garnet]

40cm Classical Cassegrain

6" refractor as sub scope

[coarse aspen]

I don't speak cm sorry

O thanks

[onyx garnet]

Oh uh

"?

About a 15.7" classical cassegrain with a refractor as a sub scope

[coarse aspen]

Is that your university telescope

[onyx garnet]

Science Centre

[coarse aspen]

So yes

?

[onyx garnet]

I have a Sky Watcher 102mm Cassegrain and a Bresser Messier 6" tabletop dob otw

[onyx garnet]

Uh I said science centre
Not university

And i'm 15

[coarse aspen]

Science center of a university?

Or just a science center

[onyx garnet]

Just

[coarse aspen]

Ok ty

[knotty salmon]

screw those cat toys

[topaz elk]

what do u use then?

[knotty salmon]

DIY collimation cap

[fading plume]

Yeah I can align my scope perfectly using the out of focus star method. I slap my laser on there and it’s wayyy out. If I collimate with just the laser I can see it’s out of collimation if I try to use it visual.

[fading plume]

why is it alwasy good seeing during clouds

[molten kettle]

alwasy

[hasty hull]

39 m/s

[peak lance]

clouds form in slower stable air

[fading plume]

thanks physics

very cool

[ebon sage]

That’s bad ?

That’s normal

[hasty hull]

I mean same

But good would be like <20

[molten kettle]

Agreedable

[ebon sage]

?

[robust knoll]

my first pictures of saturn, i am gonna retry tonight and hopefully get a clearer image

just curious, what ISO speeds do you guys use for planetary imaging? and how many exposures do you try to get?

[molten kettle]

I just record the planet moving across the screen so that a couple times, then import to you computer and stack, then process

[robust knoll]

awesome, thank you!

[fading plume]

Jups and Ganymede

[sharp ridge]

[robust knoll]

just checked my scope's collimation.... it was not good at all

hopefully i'll get some better images tonight

[fading plume]

amazing.

OMG!

GIB DAS SCOPE!

My 2nd attempt on Mars. Is ok i guess.

[sharp ridge]

this year?

[normal forge]

Nah sadly not. Mars is not in my view. 😦

[sharp ridge]

ok as its tilt is not this years one, looks pogg tho

[normal forge]

this is mars right now in my view

capture right from .ser video

it is very low on horizon, directly next / slight above a house ( city center ) and our nightsky has a weird thin haze layer.

i can basically see planets and brightest stars through that haze. its here every night.

situation is right now that i can barely see 10 stars in southern sky.

[jolly ice]

can someone help me process my jupiter's data?

[normal forge]

thats why i was happy with that image through the haze with the new 678MC. 😄

[jolly ice]

[jolly ice]

yes sure

uhhh i use a phone camera 💀

[normal forge]

ahhh ok

well lets go: speak easy voice channel.

[jolly ice]

Best I could get

[jolly ice]

can you give me 5 mins

[normal forge]

sure

@sharp ridge I had a nice conversation btw. about camera, pixel size and my "location situation". 🙂

Result: MORE APERTURE 😄

[jolly ice]

@normal forge @sharp ridge stack

do send your image too

[jolly ice]

Jupiter

[normal forge]

@jolly ice Thats all i can do.

The histogram initally is not that good. Not sure uf Jupiter was perfectly centered in the whole recording ( negativ impact from the eyepiece on the recording can happen ).

[jaunty flame]

Eye piece projection?

How horrible is it with a decent eyepiece like a tv 5mm radian?

Basically I want to have a go at planetary but I don’t have a Barlow

[fading plume]

EP projection with a really good eyepiece is alright. You can make a Barlow easily with a zoom lens if you have one.

[topaz elk]

Do you have to rotate the secondary mirror during collimation?

[peak lance]

usually to some small amount

[knotty salmon]

that’s good for us west aussies

sometimes it reaches 300km/h

[robust knoll]

My first picture of jupiter! gonna go back out and get a longer video and retry 🙂

[jolly ice]

thank you !

[fading plume]

Remember, don’t record for longer than 5 mins or so

[fading plume]

@somber stratus how bright is the ISS? I think it’s above Saturn yeah? So Jupiter settings?

According to the local Facebook group tonight’s gonna be a bright pass or something if that happens

But then it’s fast and I’m gonna be hand tracking so like 1ms or lower subs and just get my gain to Jupiter level or something

[plush sonnet]

ISS is almost as bright as jupiter

[jaunty flame]

Alright

I do have a couple zoom lenses but they’re all rather expensive

Not exactly worth taking apart for a $50 Barlow

[sharp ridge]

ISS brighter than jupiter

[fading plume]

wat setting

shortest exposure on my camera is 0.5ms i think

[somber stratus]

Venus settings

It’s bright bright

0.2-0.3ms is preferred

[fading plume]

ok cool

i was gonna try it tonight but

[normal forge]

What setting do you guys use on Jupiter? ( @sharp ridge )

[sharp ridge]

I use 15ms and 300 gain

something like that

[fading plume]

F600 moment

@sharp ridge can you do the FL measurement thing? 2.9um 1200mm base FL.

[sharp ridge]

4000mm fl

[fading plume]

thanks mate

[normal forge]

Ok! 🙂 The 678MC for me needs 12.5ms and Gain 140 with the 6".

Which cam do you use?

I hope you can sort out the issue with the screw! Any solution in sight?

[sharp ridge]

I have ordered bobs knobs but idk when they would arrive, rn we are trying to loosen the screw and temporary use the other 2 screws to control collimation but no luck so far

may take weeks to month + to get it fixed

[ruby tartan]

I use 10ms and 280 gain

[somber stratus]

yeah, 10-14 for me

6-8ms for Mars

[near quiver]

@somber stratus do you have a rec for a planetary camera, budget like $300 usd? i was thinking of a mars-c but idrk

its an untracked 8 inch dob if thats important

[near quiver]

do you have a picture of the screws

[normal forge]

Did you look into to reverse-screw-removal stuff?

The ones i sent you.

[sharp ridge]

Ye i told all of these to my parents and let them decide on a plan cuz they have good experience

Sheeesh

[obtuse yew]

What is the reason Mars requires a shorter exposure time? Because of the size?

surface brightness and also it gets affected by seeing more i find

[normal forge]

@sharp ridge I found a shop that has an ADC available! 😄 I finally get an ADC!

[somber stratus]

Ye Mars-C is the best for that budget

[near quiver]

Ok thanks 👍

[somber stratus]

Like Ken said. It’s bright & small

[obtuse yew]

What does full well mean? I'm trying to compare my ASI385MC to the Mars-C. It looks like my camera has larger 3.75um pixels, but much lower 18,700e full well

[somber stratus]

Full well is how many photons each pixel can detect before the image becomes overexposed. It’s kind of a useless parameter for planetary & is highly dependent on pixel size

Really is irrelevant to planetary

Bc you just lower the gain/exposure if it’s overexposed

[obtuse yew]

Is larger pixel size advantageous for planetary? Is 3.75 going to be better in some way than 2.9?

[somber stratus]

Not really

[obtuse yew]

Wouldn't it mean lower gain and for that reason less noise?

Also in PIPP do you guys always stretch the histogram white point to 75% and the black point to 0%

Jupiter, Sep 19th, 2022 (set 8)
Object: Jupiter

Telescope: C14 Edge HD

Camera: PlayerOne Uranus-C

Seeing/Trans: Pickering 8-9/10. Trans good - slight haze.

[somber stratus]

How did you sharpen

Looks like decon-ish

Or is that just SCT moment

[ruby tartan]

I processed the same way as always

Astrosurface>Winjupos>Registax>Photoshop

[somber stratus]

yeah but what did you do in Astro Surface & Registax specifically

wavelets? deconvolution?

[ruby tartan]

First I use the wavelets in astrosurface, de-rotate and then adjust the RGB balance in registrax

[somber stratus]

ah ok

thanks

[fading plume]

this enough overexposure for ISS?
0.2ms 30 gain

Just realised I’m an idiot. I want Jupiter underexposed

grs was from lastnight the other was from about 3 nights ago

oof my highlights on the top ill fix in a bit

[bitter bough]

Wow, very nice! Lots of details!

I've been playing with my new camera and using AstroSurface for stacking. Very happy with how this is looking! Lots of wispy swirls and such! What do you guys think?

Has to be one of my fav lunar shots nice details and it was low i wamma shoot it when its at its peak but I have school or work stupid life lol

[topaz elk]

how did you pull the hues out?

just saturation?

[thorn ledge]

Skymax 102 Azgti Mount Svbony 305 pro. No Barlow, No Filter. 500 Stacked

first try ever on Mars

tried to get rid of the blue hue

Same Setup. Second Attempt on Jupiter

[hasty hull]

[thorn ledge]

unfortnatly the pics of saturn are a complete f**** for some reason they all became way to dark

is it possible to put a dark png behind it?

a little less f**** up

all are around 500 stacked and the same set up

[thorn ledge]

tried to get the moons with a nd filter boosted the reinforcment pretty high

[fading plume]

@somber stratus @sharp ridge hows this exposure look for ISS?
