Nice work, Geoff! You have some nice detail and decent colour in the stars. Did you do anything to calibrate the colour? If you're using PI, ColorCalibration using the whole galaxy will probably work well (on the assumption that the average colour of the whole galaxy is white). You might need to bump up the saturation as well - use a Luminance mask and curves.
Nice image - I think it's probably a more accurate colour rendition than most. If you're using the pixinsight LRGB combine process in the manner recommended, where in the second step you recombine RGB and luminance, you can boost the colours by sliding the saturation slider to the left - this will give the effect you're looking for. I did that and got this slightly oversaturated version that picks out the stellar populations nicely which may be what you're describing?
cheers,
Andrew.
The repro looks great Geoff. A major improvement. As Robin notes, it does look like there is more data in there that can be tweaked further. Don't be afraid to push the data hard at least in the beginning so that you know what you've got to work with. You can then determine the strengths/weaknesses of the image and work on emphasising the good points and suppressing the bad. Colour looks spot on in the repro. I'd perhaps raise the black point more which will give provide greater colour saturation. If so desired, a light application of a high pass filter around 1.8 pixels will bring out the dark dust lanes more along with making the HII regions pop - needs to be masked to protect the stars. There is probably similar routines in PI. Overall a great result. More please.
Lots of blue now! What did you end up doing to bring it out?
Cheers,
Andrew
Andrew, I started from scratch and reprocessed taking care with colour balance.

Thanks Jase, I'll try out the high Pass filter

I find when I push saturation that the stars acquire a yellow cast - you seem to have avoided this though there are quite a few orange ones in there.

Thanks Pete, I'm much happier with the repo

Thanks Ross, I do like the stronger colour as well
