M27

Acquired in June 2015 whilst setting up my new obs. At the time, I couldn't figure out how to process the image, so the data had been been waiting for my PS skills to improve. In Dec 2015 I decided to have another attempt, however, this time I decided to try processing the star layer separately from the nebula. I also decided to change from using Maxim DL for the calibration and stacking to CCDstack2+, mainly because I've been impressed by the data rejection results of CCD stack. I also decided to separately stack the RGB channels from my OSC to see if this would improve matters. LIGHTS: 27 x 300s; DARKS: 30; BIAS: 100; FLATS: 40 all at -20C.
