NGC 2207 galaxy merger

Hi all,

Here is one of my recent RGB attempts. It suffers from my usual problems with RGB:
- Stars having halos of different colours on different sides
- Colour pixels needing to be cloned out
- Lack of "colour contrast" in the galaxy - I would prefer the centre to be more golden compared the the blue arms.

Thoughts on how to improve?

29x600s clear
19x600s red
18x600s green
11x600s blue

ST8-XME, 12" SCT @ 0.84"/pixel.

More blue data would be ideal but it's been cut short a few nights now.

I'm thinking the NABG and high noise level of the ST8-XME isn't helping my colour attempts. I'm also wondering if a better optical tube would would the clarity or star bloat.
