This is M101, the Pinwheel Galaxy, with supernova SN 2023ixf indicated by the arrow at the 2 o'clock position. Discovered by Japanese astronomer Koichi Itagak, it's a single star visible at a distance of 21 million light years (the other stars in the image are either galaxies or ones in our own Milky Way that happen to be in the line of sight). It's a Type II, produced by the end-of-life collapse of a massive star, aka "a freakin' big kaboom, hope to tell you".

About 4 hours of integration time in all, half of that on the Luminance channel, through the trusty AT8RC. Taken from my back yard in Madison.
