Version B has Ha blended into the red channel and the outer shell is brought out a little more. Ha 10x600s, 2x2 binned.

I have done M63 before, but wanted to bring out the outer shell this time. Imaged from a Bortle 2 site. L 400sx20, RGB, 250s x 8 each, 2x2 binned. I shot Ha too, but didn't include it here.

I'm a bit uncertain about the color balance as there was a slight green cast on one monitor and fine on another.
