Hmmm, compared to your original, I think you've diluted your colour depth Alex, especially with the subtle reds and Ha structures. Also, your stars and faint fuzzies are less colourful.
At the risk of being controversial - your original was
not overly magenta. It was a fine image with a good balance of colour. By all means, selectively chase down and lessen the CA visible in your stars.
