M92. 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: 44 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.

Date of capture 31/03/2016. 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 enabled 3x drizzling.
