Nice! That’s a fairly bright star observed by the NASA WISE satellite. The different rings and blobs are “ghosts” that come from internal reflections inside the telescope (eg, instead of going through a filter, some light bounces back, maybe bounces off another surface or two inside the telescope, and hits the focal plane, but not in the right place!).
