I keep seeing people crank their ISO to 12,800 for deep sky shots and it just makes a grainy mess.
Honestly, stacking ten 30-second exposures at ISO 1600 from my backyard in Boise gave me a cleaner final image than one noisy 2-minute shot at a crazy high ISO.

Tbh it's like they think cranking ISO is a magic button for more stars. Honestly, you just end with a photo that looks like it's covered in digital sand. Stacking way more shots at a lower ISO is the only real fix for that noise. I use DeepSkyStacker because it's free and gets the job done without being confusing. My first tries looked like TV static, but stacking actually makes a real picture come out of the mess.

My first deep sky attempt looked like someone spilled glitter on a black sheet. I'm still learning the stacking trick myself, what software do you use for it?
