Hi Tony. First impressions were wow I like that. Looking closer though I see that all those blue stars are more chromatic aberration blue rings.

The trick here is to run deconvolution on the blue channel to reduce the blue stars before doing the colour combine so the blue stars don't create such large halos. Or use some other star reduction technique on the blue channel only.

Another way is if you have Adobe Lightroom then it has a very good colour fringe reduction tool that gets rid of the blue rings easily. For some reason that tool is not in Photoshop. Also Noel Carboni has a reduce blue/violet halos tool but it can leave a dark ring where the blue was. Lightroom does not do that.

Lovely detail and a very good natural processing style.

Greg.
