Hello,
After the colour calibrated eye of H commented on the greenish cast

, I thought that I would try to remedy this via a re-process and here is what I came up with. The whole scene has generally moved towards the blue/indigo end, but I think that it looks more pleasing.
No science involved here, just eyeballing on a non-calibrated monitor, so the tones are somewhat arbitrary. Van Cittert de-convolution in Images Plus seems to have sent some of the smaller stars towards the maroon end of the spectrum? But after all, what’s to be expected after a 3-0 whitewash!
Cheers
Dennis
