Hey Malcolm, Nice work.
I think the colour in the stars appears undersaturated though, lots of white and not much colour in what is a what is a glorious golden field.
The Flouro effect you refer to appears to be the result of lack of detail and oversaturation imo. You can tell because the jet isn't showing - probably a consequence of the short integration time.
Reckon you're doing great, and keep adding to this one as heaps more data will pay handsome dividends
