No its exactly as it came from the video camera. All I did was to capture 50 frames of 10 sec with virtual dub, then 50x10 sec dark. Put them through Deepskystacker and adjust levels with PS. I really want to do 1 min integrations with this camera which is rated at 0.00002lux at f1.4. The masterdark is quite noise free (see attached) but a 1 min integration is blown out of the water by the light pollution from Brisbane and a full moon at the same time as the frames were captured. Brisbane was right in the same direction of the nebula when captured - so I was limited to 10 sec shots. If I manage to get to Leyburn then I will try several minutes integration just to see how far I can push the whole thing, while autoguiding.
