misty belfry thanks, i try to edit as much data as i can get my hands on...really enjoying it

u can get some really good data to work on from data.bortle.org

#

and there are tutorials for how to process on yt too

misty belfry Mar 16, 2026, 6:37 PM

#

wow there is some amazing data on there

#

i like editing data from discord, a lot more data on here would be closer to the data i can capture if that make sense

#

i am in a bortel 8 may be 9 zone (south east london, uk)

#

and i am very new to it all, so really just edit as much as i can to lear as much as i can

#

how do yall get stars so colorful bro?

#

mine are like bland asf

edgy hill Mar 16, 2026, 7:28 PM

#

I use star stretch.

clear mist Mar 16, 2026, 7:45 PM

#

edgy hill I use star stretch.

is this like a script?

edgy hill Mar 16, 2026, 7:52 PM

#

Yeah it's from Seti Astro, I use it in Pixinsight

clear mist Mar 16, 2026, 7:54 PM

#

ohhh

#

also like

#

when u remove stars

#

it kinda like removed a chunk of the background with it

#

how do u tackle it?

#

cuz like without doing nothing when u finally go to like add the stars back those background chunks create like weird halos around the stars

#

looks bad

#

fr

edgy hill Mar 16, 2026, 8:00 PM

#

Hmm. I don’t have that issue in Pix using StarX

clear mist Mar 16, 2026, 8:15 PM

#

starnet really mid bruh

#

like look at the starmask it made

#

like wtf is this bruh 😭

#

entire background is gone bruh

edgy hill Mar 16, 2026, 9:51 PM

#

Hmm

visual scarab Mar 16, 2026, 9:59 PM

#

clear mist like look at the starmask it made

ig thats phantom signal, interferes nothing in the real data

clear mist Mar 16, 2026, 9:59 PM

#

visual scarab ig thats phantom signal, interferes nothing in the real data

whats that?

visual scarab Mar 16, 2026, 10:00 PM

#

like when the software gets the star out but it also gets some signal with it, but its like not visible when u put the images back so dont change anything

#

if u do stretch the stars too much they might apear tho

clear mist Mar 16, 2026, 10:01 PM

#

visual scarab if u do stretch the stars too much they might apear tho

yea that's the problem tho like when adding back stars I have to stretch and these forms these halos 💔 💔

visual scarab Mar 16, 2026, 10:01 PM

#

yeah

#

Lots of IFN in there

#

very good

clear mist Mar 17, 2026, 7:02 PM

#

oh man

#

my workflow aint turning out good

#

lmfaoo

#

i am fkin around and finding out but like it takes so much time man 💔

clear mist Mar 17, 2026, 8:47 PM

#

visual scarab Lots of IFN in there

btw how do u get the background so smooth?

#

mine turns out all grainy

#

for some reason 💔

visual scarab Mar 17, 2026, 8:48 PM

#

clear mist mine turns out all grainy

its pretty grainy tbf

#

but i use either deepsnr our graxpert denoise

clear mist Mar 17, 2026, 8:50 PM

#

bro i ran graxpert at like max strenght

#

there are still grains 💔

#

idk if my graxpert is broken or some

#

lmao

visual scarab Mar 17, 2026, 8:51 PM

#

man grains are normal

#

zoom in on my img

#

if the img is too smooth it aint very good

#

might be little but grain in the images is 100% normal and usually good when in good amounts

#

graxpert does let some grain on the images on purpose so that its not too smooth

clear mist Mar 17, 2026, 8:53 PM

#

visual scarab man grains are normal

yea but like

#

when u actually go to like subtract red from Ha

#

those grains make this nasty red noisy pattern

#

which cant be removed by BGE

visual scarab Mar 17, 2026, 8:57 PM

#

well mb just denoise each image before subtraction

#

thats what i did

clear mist Mar 17, 2026, 9:00 PM

#

😭

#

i deleted my denoised Ha

#

by mistake

#

💔

#

yea i aint doin allat

#

ts pmo

visual scarab Mar 17, 2026, 9:47 PM

#

Bruh

#

sad

clear mist Mar 18, 2026, 4:24 AM

#

maybe will try a Lil later

clear mist Mar 19, 2026, 6:14 PM

#

this image is outta focus bro

#

the stars are wayyy too bloated

#

like 6-10px of FWHM on the smallest unsaturated stars

#

for WO redcat 51 and IMX585 it should be within the 2.5-3px range

#

ok not focus

#

lol

#

but bad tracking

edgy hill Mar 22, 2026, 9:35 AM

#

clear mist for WO redcat 51 and IMX585 it should be within the 2.5-3px range

Not a Redcat though
