I didn't see Paul's original question, except as quoted in CL's reply, however I think you may want to look at STSDAS. This package, developed by the Space Telescope Science Institute (STScI) is installed as an extension to IRAF. I know there was a lot of work put into deconvolution routines prior to the first repair mission. Whether they would be useful for Paul's needs is beyond my realm of knowledge. The good news: Both IRAF and STSDAS are extremely capable and available at no cost. The rest of the story: These are packages intended for professional researchers, and they have steep learning curves. Also, IRAF harks back to the days of mainframes and batch processing, and the user interface shows its heritage.
