Paul....I really like this rendition.
I tend to think the outer extremes of M8 are more red, and the inner, more magenta (due H-Beta) but this is neither here nor there.
With M8 it's often a case of dealer's choice, but the fact of the matter is, you have nailed the focus, guiding and colour extremely well. A top shelf result for sure! The world doesn't need more fuzzy M8's
Well done
