It's not great, but I'm re presenting this after lots of work ironing out as many of the bugs as possible. Processed in Pixinsight, including calibration, registration and integration.
The difference with this result is just a matter of doing all the major fixing while the image was linear - different star size between channels. Stars in R channel were morphed up to match B and G channels - later morphed down. Besides removing gradients and colour calibration the background was enhanced, which improved image response to colour saturation while reducing noise propagation throughout processing. Finally, rescaling the L* channel gave the image a contrast lift.
The aim was to tease out as much detail as possible, consistent with saturation without blotting out finer structures.

If you got this far please feel free to provide constructive criticism.
If anyone is interested in the PI work flow I'll be happy to post.
