A good result, Dunk. Despite the test shots I reckon it qualifies as a first light
Here's one processing idea: apply a star mask and use one of the wavelet tools, say MMT, to remove the first few layers with Chrominance as the target. Then use CurvesTransformation to bump the saturation back up if needed. For extra bonus points use ColorSaturation if you want to target specific colours. Done carefully this will blur the star colours to fix coloured rings and colour up the white cores a little.
Cheers,
Rick.
