NGC 891 data from Nov/Dec 2012 being processed in PixInsight 1.8. Top image is preliminary
luminance and bottom is preliminary lrgb combination. Due to the absence of the raw bias and flat
calibration frames, master bias and flat frames created by CCDStack2 in 2012 were used in PI to calibrate
the raw light frames. Current dark frame masters were created in PI, and all other processing was done
solely in PI.
