M1 The Crab Nebula
Seasonal Favorite, remnant of a supernova recorded in 1054. First in Messier's great catalogue of Deep Sky Objects -- not because it is biggest or brightest, but because it was the first fixed feature of the sky he observed when searching for Halley's Comet.
Tech Stuff: Borg 71FL/1.08x Borg flattener/ZWO ASI 1600MC/IDAS LPS-V4 filter. Captured with SharpCap 3.2 as 4 second exposures collected in 4 minute livestacks. Total integration time 92 minutes, processed with PixInsight and ACDSee. From my yard in Westchester County NY 2 Nov 2019.
