I tried stacking 50 photos of the Orion Nebula and it looked worse than my single shot

Everyone says you need to stack dozens of images to get a clean deep sky photo. So last month, I spent a whole night with my basic DSLR and tripod taking 50 one-minute exposures of M42. When I stacked them in DeepSkyStacker, the result was a noisy, soft mess with weird color bands. My best single frame from that night was actually sharper and had better contrast. I think maybe my tracking wasn't perfect, so stacking just added all the tiny errors together. Has anyone else had stacking make things worse, and what did you do to fix it?

Ugh, I read that bad alignment can totally wreck a stack. Maybe check your star detection settings in DSS?

Did you try lowering the star detection threshold? That fixed my blurry stack last week.
