My uncle in Flagstaff said to stop cranking the ISO past 3200 and my Andromeda shot finally came out clean
He shoots with a beat up Canon 60D and has been doing deep sky stuff for 9 years, so when he said higher ISO was just adding noise I kind of brushed him off at first. So I shot Andromeda twice last month, once at 6400 and once at 1600, and the 1600 stack had way less grain after I threw the frames into DeepSkyStacker. Turns out he was right and I wasted a whole clear night at the Grand Canyon overlook chasing brightness. Anyone else find their sweet spot ISO is lower than the youtube guides say?

Thought cranked ISO was king til my 800 stack beat 3200 every time.
