NGC 7331 or Caldwell 30. Galaxy with a recent super nova that was still visible on September 8th, 2026. The Supernova is just below the galaxy core in this image. The Supernova was first observed mid July, so by September it has faded quite a bit.
Also visible is Stephen’s Quintet galaxy cluster in the lower right. Image taken with Celestron XLT 150, Coma Corrector, ASI2600MM with LRGB filters on an AM5 mount.
