A guy at the star party in Joshua Tree told me to stop stacking so many frames, and my photos got sharper
I drove out to Joshua Tree for the monthly star party about 3 weeks ago and ended up sharing a table with a retired optician named Frank who had a beat up 8 inch dob. He looked at my laptop screen where I had stacked 240 frames of the Orion Nebula and just said "you're stacking noise, not signal" and told me to try 40 to 60 good ones instead. I figured he was full of it but tried it on M42 the next clear night and the core detail honestly looked better, less mushy than my usual 200 frame stacks. Now I'm second guessing every tutorial I've watched for 2 years. Anyone else get told to shoot fewer subs and actually like the result?

Learned this the hard way with my dslr when my subs were only 15 seconds each, so 200 of them still meant 50 minutes of total time but half the frames were junk from planes and satellites. Frank is right but I bet the real win was him making you actually cull your frames instead of dumping everything into the stacker. Backyard astro is mostly just picking the good 20 percent and throwing the rest out, lol.
