M81 M82 LRGB v1 (lowpass DDP in Maxim, iterative curves / levels in PS)

Same data as v1, (4 x 5mins x LRGB) but used the Digital Processing filter in Maxim (lowpass kernal) to bring out the fainter structures, then a few iterations of curves and levels in Ps whilst all the time being mindful of the severe gradient.

Finally used NeatImage to reduce the noise

My flats do not seem to have evened out some other defects either, so might have to re-do those before my next session (vignetting, green cast in bottom center and blue cast center right).
