help with stars

[halcyon cradle]

could someone run this image through his Pixinsight. The couod and kit lens is not the best combination for good stars but I'm positive that NoiseX or StarX can do smth.
here is the file: https://drive.google.com/file/d/1ABMDIQWRIMig2QLAnrMVxvPtdyDtal_t/view?usp=sharing (it has no color correction or backgroundextraction yet, just the raw stack)

hey @worn holly i don't mean to annoy you and I hope I don't but ik you managed to really help my image in the past. The stars are basically the same as in the orion image. They my lens gets pinched optics in the cold and combined with CA it gets really bad. It would mean the world for me if you could run it through StarX and maybe NoiseX :D

[worn holly]

Hi sure I’ll run it through for you in a bit

I think I still have access to the starX trial lol

[halcyon cradle]

that would be lovely

[halcyon cradle]

did it work?

[worn holly]

sorry i haven't done it yet, planning on doing a bit of processing later so i'll run it through then if that's okay

[halcyon cradle]

sure no problem. I did not mean to pressure you

[halcyon cradle]

hey, I'll be offline in about an hour. It would be very cool if you could starx until than :D

[worn holly]

I’ll do it now

[halcyon cradle]

yaaay

[worn holly]

starX hasn't worked great unfortunately, due to the aberrations i think. noiseX worked really well though as far as i can tell, will send the links to the starless version and your stars in a second

https://drive.google.com/file/d/1uh8lDqYLhkVnPvnVe2DdLqzHzxA-afSH/view?usp=sharing - stars

https://drive.google.com/file/d/1EuRGdGVMbw7WjWwVfd5de32C3vkBbBJz/view?usp=share_link - galaxy

i'll run through a full process of it to see if blurX can do anything to help

[halcyon cradle]

thank you so much

[halcyon cradle]

alr

[halcyon cradle]

I mean if you ignore the stars than the Data is not bad I think

[worn holly]

yeah it's pretty good looking at it

[halcyon cradle]

thank you

[worn holly]

lots of small galaxies in there so maybe a starless image would work best

[halcyon cradle]

there are a lot but Starnet thought some were stars

[worn holly]

what lens are you using btw?

[worn holly]

yeah it sometimes does that, might see if there's a way to tweak the settings

Sometimes Starnet and StarX perform differently so i might run both to see which preserves the galaxies the best

[halcyon cradle]

thanks for your work !

@worn holly I think starnet did not work

OR should I erase does away? there some in the galaxy too

you see?

did you alr do back extraction?

[worn holly]

no just noise reduction and starX. the issue there is the coma from your lens, i'm not sure if there's any work around

since starX and starnet will be trained on round stars they sometimes will struggle with coma and star trails

i'm having a proper go at processing it now. unfortunately there is some issues with the coma that BlurX can't correct fully but it seems to have reduced it a bit - will see if starX works this time

[halcyon cradle]

my starnet removed the stars in the galaxy

[halcyon cradle]

oke!

[halcyon cradle]

it does not like background xD

[worn holly]

i'm having similar issues lol, hoping to correct them

[halcyon cradle]

banding and removing green noise helped a bit

[halcyon cradle]

those are the same files

[worn holly]

crap

one second

[halcyon cradle]

No problem

[worn holly]

so it's the stars one you need right?

[halcyon cradle]

yep

I think I need a heat strap and stop my lens down more

[worn holly]

were you getting dew?

alright good news starX has done a better job the second time around lol

[halcyon cradle]

a bit bit as soom as I did I stopped imaging for a bit

[halcyon cradle]

lets go

[worn holly]

if any of the data was shot through the dew that might be causing some background issues. it doens't look too bad though

[halcyon cradle]

But I get pinched optics in the cold

[worn holly]

are you using the lens on the fastest setting?

[halcyon cradle]

thats why I think a dew heater could help

[halcyon cradle]

it was stopped down to f/6.3

[worn holly]

ah yeah if it's cold it's good to have them on, stops frost and stuff too

and what's the fastest it goes?

[halcyon cradle]

it was not. I don't have one

[halcyon cradle]

f/5.2

[worn holly]

hmm it might be worth stopping down a bit further but you've already gone quite far there

maybe try f8

[halcyon cradle]

As I said I should stop down more

[worn holly]

that's what i got

and unlike last time i have saved the tif so i'll share that with you in a second

https://drive.google.com/file/d/10br-mdwEeB4iAy0Rnb7AC0unOn9kyT3-/view?usp=sharing

[halcyon cradle]

that looks awesome thank you so much again. I'll share my process once I'm finished

[worn holly]

thanks for sharing the data!

[halcyon cradle]

@worn holly I think it turned out pretty good

[worn holly]

looks good! you've brought out some really nice detail in the galaxy there
