Crescent nebula (Caldwell 27)

[short dome]

Have fun

430mm 2.9um

[muted mauve]

wait what

[short dome]

wtf

[muted mauve]

is it like that for you?

oh now the other one is gone so ig the answer is yes

[short dome]

yea i deleted the other one

weird

[muted mauve]

alright i might aswell reprocess this later

[short dome]

ayy nice

[muted mauve]

btw to get the natural star color you gotta make the stars really green and run scnr on them

and then just saturate

[short dome]

fr?? life hack omds

gonna try that now

[muted mauve]

bout this green

not too much but not too little

after scnr they will be pretty much white so you gotta saturate a lot

[short dome]

did u use curves to make them this green?

[muted mauve]

yep

[short dome]

alr imma try it

[muted mauve]

you can also play around with the green and blue after saturating because the stars might be yellow and cyan

for blue stars for example:
more green = more cyan, less green = darker blue

[short dome]

bro is megamind omds this is so smart

[muted mauve]

lol

i mean

[muted mauve]

also for orange stars
more green = more yellow, less green = more pinkish

that was nerdy

[short dome]

i like the colours you produced, look very vibrant but natural

[muted mauve]

ty

BROOOO

MY ICECREAM MELTED

[short dome]

LMAOOO RIP

[muted mauve]

i wasnt paying atention grrr

[short dome]

i will pay my respects

[muted mauve]

lol im bored so here is the entire process of natural star colors

[short dome]

bro u should make a video on it it will go viral lmao

[knotty kindle]

instead of DBE try gradientcorrection

its better

[knotty kindle]

i wrote a script for repairing star color

[short dome]

oh fr? How much better?

[gentle sierra]

@short dome heres my fairly mid process, hope you enjoy!

[short dome]

can you send it?

[short dome]

WOWZA

[gentle sierra]

Bros got it figured out too

[knotty kindle]

a lot better.

[knotty kindle]

[muted mauve]

what exact benitifits does it have

[knotty kindle]

i dont have web hosting yet :)

[knotty kindle]

in denosier works only color denoise, i need to repair it

let me know if you loke my scripts

[gentle sierra]

Its not "better" DBE has alot more control than GC so actually DBE has better odds of successfully removing gradients without damaging data than GC, not saying GC is bad, but saying its better is wrong

[knotty kindle]

for me its better

[gentle sierra]

Can just mean youre using DBE in the wrong ways (:

[knotty kindle]

you know it depends how strong gradient you have

[knotty kindle]

im just lazy :)

[visual shadow]

upload speed is in the dumpsters

[gentle sierra]

Fair XD

[knotty kindle]

another way its the graxpert, but its not that great for me

[gentle sierra]

GraXpert is similar to DBE, but imo worse as again you dont have the same control

[hot hawk]

so red

[knotty kindle]

graxpert makes weird color spots on background

[visual shadow]

deepfried to hell and back

[visual shadow]

how did you get that Oiii such a nice colour 🥲

[short dome]

actually nice but the oiii mask has not been blured

[visual shadow]

i had no oiii mask ☠️

[short dome]

no blue mask???

[visual shadow]

i was doing random crap in ps, dont remember doing any blue masks

shouldve prob processed this as a nb image with ha being seperate and then combining b + g for HOO in the end

[short dome]

ill do a hoo later

[knotty kindle]

rah

[short dome]

ur internet speed is cookeeed

[short dome]

@eager tide nerd him look at his astrobin

[knotty kindle]

im begging for fiber

[knotty kindle]

at mine?

[short dome]

yea

[visual shadow]

yeah hoo makes more sense ☠️

[muted mauve]

im about to send a banger for people with no pix

for people who are lazy or don't have deepsnr here is the data with deepsnr applied and PCC

preview

[knotty kindle]

ill show you my color denoise script on your image

[visual shadow]

why not just acdnr for color noise

and deepsnr takes care of the noise here anyway

[knotty kindle]

and here star repair script

final image

[short dome]

much better

[short dome]

ay thanks man

[visual shadow]

im just gonna smack the hoo crescent on the existing process, i cba

[knotty kindle]

how did you make stars so sharp

[short dome]

That’s really nice, nice reds! and bg

[muted mauve]

wdym thats just the data but denoised and color calibrated

[visual shadow]

☠️

[knotty kindle]

mine edit have soft stars as hell

[visual shadow]

mine too, it aint that bad

[short dome]

prolly one of ur scripts

[knotty kindle]

what pixelmath command you use tho combine stars?

i use combine(star_mask,$T,op_screen())

[short dome]

mtf(~m,(mtf(m,starless)+mtf(m,stars)))

m= 0.999

[visual shadow]

h

[short dome]

now the colours don’t matchhhhh

make the bg lighter or smthing

[visual shadow]

or cook the shit out of crescent :)

[short dome]

that works lmao

[visual shadow]

not sure what to do about the white regions, kinda just have to leave em there

[short dome]

better

i like your process, after the 100th time of doing it

[visual shadow]

thats just how processing goes

[muted mauve]

omg the extracted luminance looks so good

[visual shadow]

think ill crop and and export as png now

[short dome]

lmao luminance being luminance

i posted somebody’s version on insta but forgot who’s it was

[visual shadow]

good one

[short dome]

skibidi

[muted mauve]

reprocess

it doesnt look like it changed at all but it did

[short dome]

a tad purple, mabye pull back a bit on the blue?

[muted mauve]

nope since its 10:30 pm so its getting dark and i wanna do some visual sketching on m27 tonight

[short dome]

oooo nice

[muted mauve]

i gotta wait for my eyes do adapt to the dark tho of course

so that will take another say 15 minutes (atleast)

to fully adapt it will take like 30 minutes

[short dome]

is it dark for you already?

sun just set for me

[muted mauve]

yeah

definetly not astro dark but pretty dark

[short dome]

i don’t get astro dark this time of year so consider urself lucky

[visual shadow]

🧑‍🍳

[short dome]

i will say, this is nit picking but the oiii looks a bit too sharp, and it’s also affecting the stars. But that’s minor and u can replace the stars quickly if u want

lmao i saw that

[visual shadow]

stars?

[short dome]

Yea they look a bit clipped

[visual shadow]

oh yeah they definitely are, have been for a while

if you zoom on em it gets real bad but just dont

[muted mauve]

https://tenor.com/view/desmondpacito-cooking-chef-gif-12378159

[short dome]

lol nice colours tho

[muted mauve]

now cya since im turning off my computer

to bring it outside

[short dome]

cya

[visual shadow]

think i can set up tonight as well

[visual shadow]

as long as you dont zoom, everything is fine

[short dome]

i might be able to but im too tired icl

fk it imma setup

[visual shadow]

dont you get astronomical twilight all night, if so thats completely fine, its basically astrodark

[short dome]

pretty much, from 11:30pm to 3 am

but my setup eats into that

[visual shadow]

start earlier

[short dome]

sky no dark

[visual shadow]

you can easily begin in nautical twilight lol

[short dome]

clouds

[visual shadow]

[knotty kindle]

reprocessed today

[short dome]

oo la la nice

[gentle sierra]

Whoops missed this XD stretch blue with some green, if you only stretch blue you dont get the teal colour

[short dome]

@river cobalt

[muted mauve]

imma experiment a bit with this data

since my last 2 processes were nearly the same

[plucky sphinx]

@short dome

[short dome]

wow thats strong, bg is a tad bit red and bright for my taste, but its a punchy process. How did you find the data?

[plucky sphinx]

I always go for punchy that's my style

As for what you're asking im not sure what you mean

[short dome]

was the data easy to process? Was it hard? Did you find any specific things difficult?

[plucky sphinx]

Very noisey but nothing graxpert can't fix

Data was pretty easy

[short dome]

what software did you use?

[plucky sphinx]

Siril, lightroom, graxpert, photopea

[short dome]

Ah, nice man

[plucky sphinx]

Since you prefer less saturation here's an adjustment

[short dome]

the sat curve was fine it was the red curve that was a bit strong for me, possible push it down a bit? Thats my taste tho its ur proces

[plucky sphinx]

nah man sorry im gonna move onto other data sets here

im getting back into AP after almost a year and need to process again for practice

so gotta move through these

[short dome]

thats fine im not rlly asking u to do anything im just giving my opinion, have fun processing

[short dome]

some more ppl do this pls and thank u

[muted mauve]

i mean

i can do it again

[short dome]

yes pls

[atomic rune]

those RGB stars?

👀

[short dome]

invert scnr but i have the rgb stars, gotta stack them tho

somewhere on my mini pc

[muted mauve]

i may or may have not forgot about this

[short dome]

lmao

[atomic rune]

Yeah same here

[short dome]

bro 😭

is my data that forgetful

[atomic rune]

No discord made the forum disappear way faster than the rest of the forums I engaged with.

[short dome]

discord don’t like me fr

[atomic rune]

Yup

[atomic rune]

alright i downloaded it

time to give it a shot

im immersed in mount research atm

[atomic rune]

I didnt realize you could do invert SCNR on the stars and theyd come out nearly RGB

ive been pretty bad about keeping that Ha in the background even on my own data as of late

mostly because i feel that im having a hard time getting the contrast i want since the background here is actually fairly bright

[cedar turret]

I don't like it it's very noisy I'm sorry @short dome 😦

[versed dirge]

@short dome

[versed dirge]

not too proud of this

[short dome]

bump

[short dome]

boop

[gentle sierra]

Retry???

[short dome]

yesssss

this data does well at 100% bx btw, just gonna leave that here

[short dome]

fool me once shame on me

[gentle sierra]

Ain’t no fooling, just was tired last night and don’t wanna give out a mid process

[short dome]

fool me twice shame on you

[gentle sierra]

Doubt me once, shame on me
Doubt me twice, shame on you

@short dome

Ngl pretty happy with this process, crescent itself could be a little better, same with stars, but everything else is great

[muted mauve]

woah that that oiii looks so good

[short dome]

HOLY XHIT

[gentle sierra]

[atomic rune]

Cygnus best constellation after Orion

[short dome]

starxed blurx deepsnr tif

[short dome]

my current process, thoughts?

[gentle sierra]

I like it alot, but that OIII looks very dark

[short dome]

there isnt thast much o3 🤷

[gentle sierra]

No not the stretching, the colour is dark

[short dome]

Ah okay, so push o3 brightness?

[gentle sierra]

Brightness and maybe some G in there to make the blue more teal too

[short dome]

alr cool. anything else?

[gentle sierra]

Nah I quite like it otherwise

[short dome]

cheers

[short dome]

bump

[manic tinsel]

Hello. I am brand new to astrophotography, and this is the fifth edit that I've done. Any advice is appreciated

[short dome]

i like the natural look. What where the steps u did in your processing?

[runic glacier]

filter used ?

[short dome]

svbony sv220

[runic glacier]

Ty

[manic tinsel]

backround extraction, color calibration, sharpen and denoise, then just curves

[weary sundial]

Yeah, it’s a neat trick

[short dome]

bumpy bump

[rich relic]

I think I have to process this too just to make this the nb 1 #1021002743080558642 thread

@short dome

what do you say

[short dome]

lol na it’s not deserving

[rich relic]

I wanted to process your data anyways

But Ill probably only find time at the weekend, 2 exams this week
