[wet star]

lowk love processing M51

its soooo beautiful ngl

i might not be able to process it better than u prolly

but imma try

broo there are like Ha blob in this too

[foggy palm]

It doesnt matter, i would like when you can try more get color i mean blue.

[foggy palm]

I will shoot it too

[wet star]

ohhh

like the purplish glow?

u can use human weighted luminance in GHS for that

[foggy palm]

i dont know that can you try later process it?

[foggy palm]

i mean blue this galaxy is more blue on my processing i isnt and idk why

[wet star]

ohhhh

imma try that

[foggy palm]

ok

[wet star]

aight

here is my take

also i jst realised that there were artifacts from my decon 💔

[foggy palm]

Good but it is purple can you try do blue?

[wet star]

aight

imma try that

this good?

ngl sidivis might be able to help too

@charred ridge u wanna take a shot at this? 😊

@marsh pendant good data over here

[foggy palm]

Still purple but ok

[charred ridge]

Sure I'll take a gander shortly

[wet star]

goat

[charred ridge]

Honestly, imo, this is a pretty good process the color is all there you just need a few saturation boosts. The blues all look natural and you shouldn't really need to do anything crazy with curves to make it come forward. I got about halfway thru my process and things crashed... I'll finish it up later or tomorrow morning with coffee.

[foggy palm]

ok

[marsh pendant]

Hmmm might try

[wet star]

W

[charred ridge]

@foggy palm prolly coulda tuned the HDR and stretch for the core a bit better

great data for 7 hours

[foggy palm]

broo

how can you tell me what process did you use?

[foggy palm]

can you send me processed?

[charred ridge]

Yeah I'll send it over tomorrow

[charred ridge]

It was all done in PI

[marsh pendant]

@foggy palm ABSOLUTE CINEMA BROTHA

[foggy palm]

can you send me?

[marsh pendant]

i can try

its sending ig

80mb's xisf

[foggy palm]

thx

[marsh pendant]

why do u want it tho?

not final tho, it doesnt have the last contrast thingys

[foggy palm]

only for look

[charred ridge]

@foggy palm

oops wrong one

[foggy palm]

thx

[sterile yacht]

🤯

[marsh pendant]

I might retry this data

[foggy palm]

how did you do colors can you send file pls?

[wary lichen]

Yep that's the blue I was talking about

I'll try to process it when I'll have access to my pc

[wary lichen]

Also you got the very nice dust around the galaxy!

[sterile yacht]

no problem, I just have to edit it again because I didn't save it

[foggy palm]

can you tell me how did you do blue galaxy?

i mean color because i try it but i had it too much bad

[wary lichen]

I did basic lrgb composition, bge and spcc and the galaxy looks good, blue

Basic autostretch view in siril

[foggy palm]

Ok thx i didnt know that❤️

[foggy palm]

Can you tell me how to apply autostretch linked and unlinked

?

[wary lichen]

This button toggles linked/unlinked

[foggy palm]

I know but how to apply linked and unlinked autostretch

[wary lichen]

Idk lol I don't use autostretch to stretch

[foggy palm]

Ok

[wary lichen]

Don't you use ghs?

[foggy palm]

I thin no

[wary lichen]

Oh

Generalized hyperbolic stretch

[foggy palm]

What is that?

[wary lichen]

A tool to stretch that prevents clipping / blowing out details

[wary lichen]

What do you stretch with usually?

[foggy palm]

Mannualy or autostretch

[wary lichen]

Histogram stretch?

[foggy palm]

Yes

[wary lichen]

Oh

[foggy palm]

Wdym

[marsh pendant]

Yep yep

MUUUCH better than what i did last time ig

@foggy palm

[foggy palm]

yeah colors are very good but its not sharp

[marsh pendant]

yeah, i did not make want to use cosmic clarity too much on this one

[wary lichen]

Honestly I don’t like when it’s oversharpened

[wary lichen]

This one looks good

[marsh pendant]

yeah fr

[foggy palm]

to be honest i really dont like because its not sharp

[wary lichen]

I agree it could be a bit more sharpened

[foggy palm]

i did everything what you did and nothing happened

[marsh pendant]

i think sharpening is good but my cosmic clarity usually kills some data, like the bg becomes noisy and details not just become sharp they become bright

[marsh pendant]

gotta saturate before adding lum if ur doing at linear

[wary lichen]

In your process the details look a bit too overkill imo

[foggy palm]

i did LRGB composition and DBE and SPEC

[wary lichen]

You’re in bw mode

Oh nvm

Did you do linear match?

[foggy palm]

ok tell me all steps what to do

[wary lichen]

Basically

I just did composition -> rgb composition

Set lrgb to the files

Linear match

Align

[foggy palm]

not LRGB?

[foggy palm]

ok i have it

[wary lichen]

If the image looks gray maybe try restarting siril

It fixed the issue for me

[foggy palm]

ok i pressed linear match and align

[wary lichen]

Nice

Now just bge

Oh crop before bge

[foggy palm]

I did spec , photometric calibration, plate solving, crop, bge but now how to apply stretch to this (i know how to apply but it gonna be more warm if i apply)

I did it

[sterile yacht]

I only use curves for color and of course spcc

[foggy palm]

but idk if it is good

[wary lichen]

Let’s goo

[foggy palm]

thx, but something is not right because unsharpness and noise got very high

[wary lichen]

Well you didn’t denoise and decon

[foggy palm]

how to use this?

[wary lichen]

Maybe this can help you

https://quark-coder.github.io/siril-guide/html/galaxy.html

[foggy palm]

ok thx for help

[wary lichen]

You don’t have to do everything in the guide

Just look at how he uses ghs

[wary lichen]

Yw :)

Also

Stretch by small increments

Don’t try getting the perfect stretch in only 2 iterations

[foggy palm]

thx

[wet star]

same

[marsh pendant]

might retry yet again, i'll try my best this time, ngl i was not happy with my processing

[wary lichen]

Yoooo how did you get it so clean

The dust looks insane

[marsh pendant]

Wdym by clean? not many highlights in the core?

[marsh pendant]

thanks man

[wary lichen]

You used pix?

[marsh pendant]

Yeah i'm on pix now

cracked tho

[wary lichen]

Ohhh

It must be great

[marsh pendant]

Yeah fr

i'll probably buy the real one by next year tho

[wary lichen]

How is it compared to siril?\

[marsh pendant]

JUST BETTER

SiriL is great but it doesnt have some hey things that change everything

like masking

and multi windown

[wary lichen]

Did you do an automated stretch?

[marsh pendant]

also the code is just so efficient that a graxpert ai denoise that on siriL takes 10 mins, in pix takes abt 1 min

[marsh pendant]

nope all manual

[wary lichen]

Damn

[marsh pendant]

i dont like the automated things

[wary lichen]

It looks so good

[marsh pendant]

thanks man

it takes a lil effort to learn but pix does the rest

[wary lichen]

When I try to add colors in siril it just separates the colors so bad

[marsh pendant]

its pretty easy to do

[marsh pendant]

Yeah siriL saturation is pretty bad

[wary lichen]

And it's very noisy

[marsh pendant]

id say to use gimp saturation, or photoshop on raw camera mode, its just better

[wary lichen]

How do you manage to use pix for free?

[marsh pendant]

i wouldnt say very noisy, but indeed has some noise

[marsh pendant]

well

a man on this server gave it to me basicaly

a cracked version he got with a friend

i can try to find it on my chats if u want

[marsh pendant]

do u want it?

Found it, if u want just dm me i'll send u the tutorial and link

[wary lichen]

I won't use it actually'

The developpers need that money

And it could be a virus anyway

I wish there was a way of using it for free tho 😅

Without a time limit

[wary lichen]

You did a ghs stretch?

[marsh pendant]

they got lots lol and i'm buying it anyway so i'm just usihng it before

[marsh pendant]

yes i did ghs and histogram

[wary lichen]

Ok

Is ghs the same as the one in siril?

[wary lichen]

_ _

[marsh pendant]

kinda but better in some ways

it can also be used as saturaion and be aplied to channels only its fun

[wary lichen]

Oh

Are the options the same? Except that

I just feel like people using pix get better results magically lol

[marsh pendant]

its better but the basis is the same

[wary lichen]

o

[wary lichen]

Hey @foggy palm , I was wondering what you used for sharpening

And denoising :)

[foggy palm]

blurxterminator for sharpening and graxpert denoise

[wary lichen]

Test, probably oversaturated and oversharpened? What do you think

[wary lichen]

These colors look so yummy I wonder how you got them!

[marsh pendant]

Selective collor correction with pix

[marsh pendant]

Thats pretty good but needs a lil more blue hue

[wary lichen]

Atp pix might just be dark magic

[wet star]

ikrrr

pix boost

lowk

even graxpert works better with pix

idk why

or how

[wary lichen]

Fr broo

[wet star]

@marsh pendant can i get the pix download like the one which u have? 😊

[marsh pendant]

yeah man but u sure?

like its good but needs some time to adapt

[wet star]

no worries

[wary lichen]

I don’t know if you can even do that with siril

[marsh pendant]

Just add blue on the histogram and run a background ext

It can fail but can go write too

[wary lichen]

That'll make it look dark blue tho

[marsh pendant]

Then add green

A lil green plus the blue will create a cian effect

If u want a purple effect just get rid of the green

A lil tho dont put it to 0 lol

[wary lichen]

mhm

The background is cooked

[marsh pendant]

Now just use background neutralization on the color calibration process

[marsh pendant]

Then i'll be fine

Or u can try to backclip it

But less recommended

[wary lichen]

Yeah I did that

[marsh pendant]

Hmm

Is it denoised?

[wary lichen]

Yep

Idk I have a weird relationship with noise

https://tenor.com/view/april-fools-joke-dog-its-fine-this-is-not-gif-16757454

[marsh pendant]

Hmmmm

Mb run graxpert dbe?

It works some times

[wary lichen]

Test

[marsh pendant]

Lol

[wary lichen]

I set red saturation to 0 lol

[marsh pendant]

BRUHHH

Worked thi

Tho?

[wary lichen]

Wait now the background looks blue

[wary lichen]

Yes

[marsh pendant]

Now turn blue saturation to 0 too

Will work just fine

[wary lichen]

Surely bro

It's not like if the whole galaxy was blue

Background neutralization is the hero
