Hmm... a little colour compared to my previous 'crabby' effort, and a richer starfield provides some context for this supernova remnant. It must have been quite a sight, outshining the midday sun and remaining visible for well over a year.
Despite that explosive start, I'm a little disappointed this didn't come out better. Although the moon had pretty well set, there are annoying gradients and skyglow, which I expect is due to some haze and rather bumpy seeing, which I couldn't do much about. On the plus side I managed to reduce the excessive vignetting and distorted stars using a shorter imaging train.
55m data with 120s subs through my NBF and 60s subs R,G,B is really not sufficient to tease out the detail and colour. I think I achieved this better using my old DSI II OSC, if limited resolution and FOV (
