Hi again,
Yes I have Don Waid's CD and went back to it after your suggestions. The smudge tool in Photoshop does a great job and is very useful on a small selection of stars but I think I would pull my remaining hair out doing this job on all the stars on the outskirts of Omega Centauri.
I also had a look through Don Waid's tutorial on "Star elongation repair using the offset filter" and went through the process in Photoshop. While it looks straight forward I was not able to reproduce the blue selection line he shows (unless it was one of his highlights) which was necessary to use as a reference point when going to the next quadrant to repeat the process.
Could you let me know how to bring up this coloured selection line (not marching ants) when this selection is made?

Thanks again for all of your suggestions so far.
