Criteria for failed image removal?

Nasa-HSIA

I'm curious about the criteria for removing failed images in SeeStar? This is because I was rechecking the images that were considered successful. However, some of these successful images still contained sub-frames where the tracking was poor due to shaking (these should be considered as images that failed tracking, but they were still saved and not discarded).

This is mainly determined through algorithm-based identification. It is necessary to judge whether the star points captured in multiple shots can overlap, and check for the presence of star trails or missing star points. Based on these judgments, a decision is made on whether to discard the shots or continue with the stacking process.

Tech@ZWO Thanks for replying. Does Seestar take the roundness of the star point into account also?
