Thanks Doug! I'm actually going to start taking some quick shots of my objects in future to capture some of the colour and overlay that like a layer mask to try to produce more colour in longer subs. Has this been tried, do you know?

Nice shot mate..
Yes, layering in shorter exposures to reveal star colours is a tried a tested method.. It works incredibly well provided its done well.. your best bet is to layer the short subs over the long subs, set the layer blending mode to either colour or soft light, create a "hide all" layer mask. Select the Hide All mask, then with a white paint brush of the right size with soft edges, systematically go through the image clicking on the stars that require a colour boost. this reveals the colour from the short sub star where the long exposure star is saturated.. Once you're done, select the layer (not the hide all mask, just the short exposure layer) apply a slight median blur to soften things up a little bit, and increase the saturation to taste...
To get the desired results you may have to then play with that layers opacity a little...
The method works really well, and when done well, is absolutely seamless. It really pays to spend a bit of time adjusting the brush size on a star by star basis, the closer the paint brush is to the size of the star, the better your results will be.
