Strange name but beautiful group of galaxies in Pegasus. The spiral galaxy in the center of the photo (NGC 7331) is easily visible in small telescopes from dark skies. The fainter galaxies in the group require larger instruments and dark skies to spot. I remember seeing at least two of them with my 16" dob but probably could have seen more if I spent more time there.

This was my first image processed using PixInsight. Outstanding piece of software. If you're an astrophotographer, I highly recommend checking it out!
