I think you should seriously consider sending the image to ESO.
I checked their copyright conditions and manipulating their images is OK.

Thanks Steven,
The difference between yours and mine is that yours would pass muster with the purists, whereas mine most likely won't.
The creation of a star mask with just the small stars is a somewhat subjective matter. The method, though highly automated, is not exact in its highlighting/masking of stars. The whole method described above is founded on principles of statistical probability and random distribution, but I cannot say for sure I am bringing to the fore only the galaxy's stars, nor can I guarantee I get all of them.
The method is good enough to approximate the galaxy's shape and star distribution. However, it is not a 100% accurate representation of reality. Then again, no image is...
