Description

My second best shoot after M33, really beautiful galaxy, whirlpools spinning all aroud with fine details.
Lot of tiny galaxies around, seems the are galaxies clusters below right and top left.
For HA, now I know I need much more than 2 hours, 4 is the minimum I think to have a good enough signal mostly for HA galaxies because it's very difficult to integrate it, preserving what is HA an none.
However I really enjoy to treat it!
Now I add the exact same process with luminance only and RGB only to see the differences.
See revision J for the full final version

Edit 29/10/2018: lit bit less color saturation and HA better realignment
Edit 23/11/2018: color correction
