This ones for the gurus. I'm trying to use PCFE to process some sunspot bmps. Unfortunately it doesn't seem to like doing it. I tried with the standard settings, but not go. I then mucked around with the threashold setting...still nothing. I then forced the process and away it went. Unfortunately it didn't so a very good job of centering the sunspot it was jumping all over the place.

Can anyone offer any suggestions? I've attached a single frame so you can see what I'm working with.

Thanks
