I've never had problems with banding in any of my stuff. YET. But, if I don't ever start getting some decent weather around here all this gear I have in my observatory is going to molder away from lack of use.

Noel has some great programs and there are also some terrific free PS astro plugins available from Jamie---?

I'm afraid if I try to get the address right now I'll lose what I just typed again. FireFox just updated and for some reason I can't return here anymore if I leave. 

The astro plugins can be found in the files section here:

Some nifty and useful add ins for PS. Only work in Windows OS though.
