Cool! And welcome! :slight_smile:

Looking at the Gaia catalog, it looks like this is two stars, the bottom one fainter than the top one. Both are relatively nearby and moving northward. The dark spot in the center of the top one is an imaging artifact - the star is bright enough that it saturates the detector, and then the image processing software marks those pixels as bad and they end up dark instead of very bright.

cheers,
