M31: The Andromeda Galaxy. 5 nights of dedicated imaging for 15 hours of RGB (combination of 45-second, 1-minute and 3-minute exposures) and 5 hours of narrowband (Optolong l-eXtreme). Honestly, I processed this about four or five times before getting to a result I was satisfied with... future revisions may come!
