Having got some Ha data through for this, I thought I would re-process it with that now included. The only thing was that I was not competent enough to be able to add the Luminance in such a way as to improve the image, so I decided not to use it at all. So, this is a HaRGB only. I used 52 reds, 30 greens, 50 blues each at 120s exposure length, plus 40 subs at 3 minutes long each for the Ha. This equals an imaging time of 6 hours and 24 minutes. Have a good night everyone.
