NGC2239 Rosette Nebula

NGC2239 and 2244: 15s subs at -20C, 139 gain and 21 offset: 89 x L, 33 x R, 40 x G, 40 x B on the Skywatcher Esprit 80 with the ZWO ASI 1600MM-C and ZWO RGB filters

This was almost destroyed by the neighbour's heating vent pushing steam across my imaging area. I discarded the worst frames but there is still a bad background. Plus I didn't have long before it went beyond the side of the house. Processed in PixInsight with some final touches in Adobe Lightroom.
