I was experimenting with different bins with this image. The conclusion for Ha at least, don't bother stick to bin 1x1. With other bins the resolution is quite poor especially bin 4x4.
But the result was ok in the end. This is basically a Ha image, but I took 10 x 1min subs for R G & B and added those in with Ha to get coloured stars. The aim of this image was to go deep and I think I managed that with lots of faint nebula.
The actual sub exposures were (taken 20151224 to 20160228) :
Ha
900s x 8 bin1
1200s x 13 bin1
900s x 4 bin4
900s x 3 bin2
RGB
60s x 10 of each bin1
Update: As my processing has improved over the years I thought I would re-work this image as it was one I was not happy with. This is a Ha image with added RGB stars, but not done very well. So I went back to the calibration and completely re-processed this image without adding any more data. The result is more detailed, stars that are no longer bloated and the right colours.
Completely re-processed
