Cygnus star cloud 1st attempt

Cygnus star cloud. 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: 12 x 5min at ISO 800, 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

Date of capture 08/05/2016. Atmospheric transparency was poor (I think something to do with lots of barbecues that day). Auto guiding was stable.

I increased the saturation by 25% and manually aligned the colour channel histograms. I stretched the red colour histogram more than the green or blue to increase its contrast. The D200 does not pick up much h alpha in the red so the result is quite noisy. I will try again on this target with more exposure to see if I can overcome it. No drizzling was done on this stack.
