Here is one of my images of the same object that has had some post processing with Noel's Photoshop actions.

Among the useful routines here would be reducing star diameters,removing background noise and colour gradients. I've found it can be a bit tempting to run too many of these actions and end up with a photo which is not very naturalistic looking. Nevertheless it's cheap and definitely worth trying.
