That's one of the nicest bicolour eta carinae's that I've ever seen. Love to know how you got that warm friendly look. (No hint of the awful magenta and purple blood and guts look that some folk get trying to reproduce natural colour.)
You've clipped the bottom of the histogram for the red and green channels, so possibly losing some of your very faintest detail and making the blacks a bit too all-or-nothing.
The sharpness is amazing. When I see a photo like this taken with a small scope, it reminds me that a huge scope at close to sea level in summer has no advantage in sharpness and may even be worse.
A nice new feature that I'd never noticed before: about 50% of the way from centre to top left, just beyond the region with the two famous HH jets (which you have captured nicely) there is what looks like a Leunig Mr Curly style wave breaking toward the left (or is it that famous Hiroshigi great wave?), above a darker cavity. Immediately toward top right from this curly wave is the very recognizable profile face of Cyrano de Bergerac.
Good stars too, except perhaps there seems to be some curious swirly artifact around eta Carinae itself.
Best,
Mike
