Much better John.

The transition from the outer wisps of nebulosity to the core is a lot smoother and aesthetic. This object is traditionally not all that red, but takes on more softer subtle tones. I feel you have captured this well. Your tracking/guiding is on the ball. I think you might get some more nebulosity in the outer regions using curves. Be sure you don't clip the white point though. Don't stretch too far as you may introduce noise in the dim regions which you'll then need to selectively smooth.
