The one comment about stacking subs that got me

I was scrolling through a thread the other day and someone said you should only stack your best 50% of subs, not all of them. I've been dumping every single 30-second frame into DeepSkyStacker for like 8 months now. That includes the ones where Jupiter photobombed my Andromeda shot and the ones where a plane flew through the frame. I reprocessed a cluster image from March with that 50% rule and actually saw detail in the outer stars for the first time. Has anyone else been wasting time throwing bad data in the pile without checking first?

I heard somewhere that some astrophotographers only stack the sharpest frames, like 30-40% of what they shoot. Makes you wonder how much time we waste polishing garbage data instead of just being more careful up front.

Is it really that deep though? I mean yeah you want good data but tossing 60-70% of your frames seems wasteful. Most nights the seeing is just ok so you take what you can get and stack it all out.
