All stars have the same defects—"pips" at the top and right.
It’s worth being more careful when selecting frames for stacking and removing flawed ones.

By the way, this applies to all of today's photos. It might not be a shooting defect, but an optical issue, such as pinching.

This is most likely due to the protective UV filter I foolishly attached to the lens. All photos taken with it had this issue.
