Description: M31 02.01.2017

30x120" lights and 3x120" darks stacked and stretched in PixInsight (trial version). Then applied Colour Correction (just accepted defaults), SNCR (just accepted defaults) and MLT (just accepted defaults). Don't know what I'm doing in PixInsight yet.

Saved as 16-bit TIF, then opened in Photoshop and increased red, yellow and blue colour saturation.

Think I've gone as far as I can on these subs, next steps are to fit field flattener, try longer exposures and autoguiding.

Had to include some darks to make PixInsight work, previous attempt without darks was better in some respects, must investigate further.
