Title: M106 in LRGB and HaLRGB, reprocessed

Description: I never was really happy with my M106, for whatever reasons had problems with artifacts in the stars (and made it worse in my previous version - I have to admit). Also Ha made the central regions of the galaxy to reddish. So I fully reprocessed. I find the result now more pleasing, in particular the Ha version (version D) with a much more subdued Ha.

Description: rather than somehow combining Ha and LRGB, I tried to more correctly only add the difference between Ha and the underlying continuum.

Title: reprocessed - without Ha (toogle Ha via mouseover)

Description: completely reprocessed the data with a modified workflow (and a lighter hand on color saturation), in particular

1) added Ha data already in linear stage
2) new workflow including NoiseXterminator
3) stretching using the fabulous GHS script (thanks @Gunshy61 and @mike1485)
4) removing and re-adding stars with screen blend rather than simple addition (thanks Russell Croman)
5) have a reasonable workflow to correct chromatic error (in particular in blue) owing to Celestron's reducer
and many more little details/experiences

Title: M106 - next try

Description: M106 is a nice large and fairly bright galaxy to photograph, but somehow turned pout to be really hard to process. This holds in particular when Ha is added. So I did (another) full reprocess.
