Here is my effort for this galaxy; I had collected most of the colour data a couple of months ago and collected the remaining colour and luminance data last week. The night I collected the luminance was generally clear, but high cloud kept hazing over periodically; about half the luminance subs were good quality and the others were average, so I used the good quality subs for the detailed areas (with high s/n ratio) and used all luminance subs for the extended halo. In all I collected 5 hrs lum and about 3 hrs for each of R, G & B. Not quite up to Rolf's magnificent effort
but I have managed to capture a lot of the extended halo as well as some good detail in the dust lanes. I believe that you can see a bluish trace of the nothern polar jet at about the 7 o'clock position from the core as well.
