That's the worst feeling, @diana_king. I spent a whole week stressed before the follow-up test came back clear. It really makes you lose trust in the whole process for a bit.

Watched a video on stacking and thought it was just for people with too much time on their hands. Tried it myself last year on a shaky shot of Jupiter and its moons, fully expecting a blurry mess. The software basically glued it all together into something actually clear, which was a quiet but solid defeat for my skepticism. Now I spend way too many nights trying to fight atmospheric blur with math instead of just accepting a bad photo.

Totally, my shop says the same.
