It does indeed work - largely because the authors wrote it to solve thier own problems. User interface is one of the things that can suffer with freeware. Linked to that though, the algorithms used in commercial ware can be less than perfect (quality wise - at the altar of usability and speed.). Microsoft, for one, appears to spend more effort getting programs to look right than work right - seriously. It's the GUI that sells not what's under the bonnet. SGBNR was written specifically for astronomical images. It does work. It does exactly what it was written to do. It's not for wimps! http://www.whirlpoolgalaxy.com/grain_removal.html "SGBNR is difficult to use, primarily because it lacks a real-time preview as settings are adjusted. It is not remotely intuitive how the various settings affect the image or how they interact with one another. It does, however, offer what appear to be comprehensive sets of controls that allow very precise adjustment of the image. To get really excellent results with SGBNR, be prepared to spend a lot of time fiddling with these settings." Bob For every difficult problem there is a simple explanation - which is wrong.
