Hi Paul -- you might look at using IRAF, or at least go to iraf.net and post
this question.

This is sort of a narrow technical question, but I could use ideas:
I'm looking for image processing programs that do "guided deconvolution" or
"inverse filtering" on photos with misshapen stars. That is, taking odd shaped
stars and making them round using the knowledge of their shape. This differs
from maximum entropy processing or blind deconvolution. But here the user
instructs the program to study the shape (2-D point spread function) of stars
in the image and then makes them round by deconvolving the entire image with
that function. It would also be nice to do this on color images without
de-layering them. This is sometimes known as Inverse Wiener Filtering.
