On 4/20 i tried to image a galaxy for the first time, and failed because of heavy winds. But with lower winds and 16 pounds of iron on my lens plate, I tried again.
It turned out so much better than the last one, which I'll show below.

Celestron Nexstar 8SE
ASI533MC Pro
Starizona x0.63 focal reducer

38.6 minutes of integration, 10 second subs

#

heres the first try with the fake colors

#

only 7.5 minutes on it

what are you using when trying to process it?

I can see plenty of stars in the sub but I was told it's because windows applied an auto stretch to them. When I open it in DSS i can see maybe one star even after messing with the pre stretch thing in to top right corner

and after stacking? what did you do

#

I used photopea (some free online Photoshop) and tried to mess with the levels and contrast and whatnot

#

I honestly don't know what I'm doing but I'm messing with stuff until I see a galaxy 💀

yeah don't use photopea, maybe just for final touches. Download siril so you can do proper color calibration and stretching

#

can you upload the stack? just to see what it looks like
