Another stunning colour image. I love this colour rendition. It almost looks like you've used polarising filters.

One comment; be careful of oversharpening the stars, they look a tad hammered.

Cheers Greg, you are so right the stars always struggle after I have been digging for details.
Must try harder at that.

Thanks,

Dave

Use masks on the stars per Louie Atalas tutorials. Its called an inverted mask. The easiest way to do it is to use Noel Carboni Photoshop actions.
One is called "Select brighter stars". That will select the stars then expand the selection perhaps 1 pixel and feather 1 pixel. Then copy them into a mask and then invert the mask so now the stars are black. Black prevents things showing through in masks and white reveals things.

Now you can process the image, and the stars are not affected.
PM me if you want and I can walk you through an example.

Greg.
