Question about the stars. They are mostly neutral in colour. I notice many NB images have a distinct cast of some sort. Did you add RGB stars at all or adjust the colour or is this just how it comes out with this combination?

Thanks, Kevin. I used JPM's tone map technique and removed all the stars before combining the colour data. The stars come back with the Lum but they tend to wash out the starless colour data and this is the result. It's possible to generate false star colours from the NB data but I didn't bother with that. We didn't get any RGB data for this target.

Ta, Mike. I did toy with more heavily saturated versions but they didn't look right to me.
The data is very heavily stretched to bring out colours in the dim background. I believe the colours are real but extremely exaggerated. I largely hold with the PI philosophy of never "painting" data or masks and, apart from CloneStamping out bits of stars that didn't get removed cleanly, every operation performed on the image was global and based on the data values.
I agree that the black area looks a little odd but it also looks that way in other images
Appreciate your honest feedback
