Sorry one last comment, I just saw the full image and saw the little source next to the star is real. You don’t see any copies of the other stars as far my eyes can see, very interesting!

I should also say I enjoy your images a lot, thank you for sharing them ✨

I was wondering that too, one way to check is if the source next to the star is real or if it is a coma as well. I imagined one of the mirror segments is not aligned well for that exposure, so there is a copy of the star, or a glare from a source outside of the view.

(Might be chromatic aberration)

Looks like one of the segments is not aligned in the focal plane when this was taken
