An attempt at NGC 55. Trying to get some more detail with my new ASI1600MM-C compared to my old QHY8, so selected the best 184 out of 241 60 second Luminance subs - those with less than 3" FWHM average. A bit of an arbitrary bound on the sharpness I guess -- comments welcome??
Couldn't get a decent non-windy night to get some reasonable RGB data so used some old QHY8 data for the colour.
Minimal overlap of the two images means I was forced to crop just the galaxy!
Full res on
Astrobin.
Still struggling with some noise in the fainter areas (edges) of the galaxy, with only 3 hours of L in the 'burbs so found it hard to process. Tips appreciated, e.g. blending that galaxy edge in more smoothly with the background somehow??
Thanks for looking.
