Hot take: stacking too many frames can actually make your deep sky photos look worse
I see a lot of people in local club chats saying you need 50 or 100 frames for a good Orion Nebula shot. I did a test last month with my 6-inch scope, comparing 20 frames to 80 frames. The 80-frame stack looked way too smooth and lost all the fine dust details, like it was smeared with noise reduction. Has anyone else found a sweet spot for frame count before you start losing real data?

Oh man, that's super interesting. I wonder if the issue was your stacking software settings, not the number of frames. A good stack with 80 frames shouldn't smear details like that, it should just make the clean parts cleaner. Maybe check your alignment or rejection settings, because you definitely want more data to pull out the faint dust.
