Managed to add some colour data to the original luminance on the weekend. I didn't bother gathering more luminance - 3.25 hours was enough - this galaxy is bright! Nor did I do any additional luminance processing - just RGB.
Colour renditions of this object vary considerably so I just tried to stay as true to the RGB as I could. I may revisit the processing but I'm rather pleased with this result.
