Excellent colour and a good sense of proportional scale. I often see M81 with unaturally large artifacts within the galaxy that immediately looses the scale grandness that a huge galaxy deserves. The effect presented here is most appropriate. Yes, I rely on decon to tighten up too, but found hrs of exposure time was needed to be able to use 30-50 iteratons without artifacts and noise over the whole image. The Ken Crawford videos you posted are excellent at selective processing, using a mix of say 2 images at 30 and right up to 150 iterations with layer masks (I guess thats what you mean by your 3 reduction masks, or was that only for noise processing?)
Thanks Jase, almost "gendler" in its smoothness ;-).
