M106 - Second attempt

M106. Processed using DSS. 

Hardware details: Camera: Nikon D200. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 53 x 3min at ISO 800 taken over 2 days, Darks: 20 x 3min 20sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100

Dates of capture 30/03/2016, 31/03/2016. Conditions: Not great: lots of clouds disrupting guiding. Seeing was OK. 31/03/2016 was far better, clear skies, no wind, seeing was reasonable. Guiding was stable but did trail on 2 subs, PA was good, I could get 1 min unguided subs. 

I increased the saturation by 20% and aligned the colour channel histograms. I also enabled drizzling which produced a far better output.
