I was going to shoot SH2-114 (the Dragon Nebula) but it wouldn't show up at all in 5 minute test shots. So I went for my next target in list, the Propeller Nebula in Cygnus. I always find it difficult to process these Cygnus nebulae, as there's not a single pixel of background sky visible. Even when I register some HA image as my reference for background extraction, I have this nagging doubt about messing with the data. At least the propeller shows up fine.
