Its at http://www.diardsoftware.com $25. At first it seems limited if you use the presets. But with experimenting, you can actually make a basic pic with it, then use that pic as only the base of creating another galaxy within it. Hard to explain unless youve tried it. Prob is that when you make lets say one lensflare star next to another, where the 2nd one stops can be a distinct line change of brightness following a straight line. Most annoying, takes a lot of work to blend out even partially but touch ups afterwards.
