I find the OIII and UHC filters to be pretty much interchangeable.
Occasionally one is better than the other but not often. I think if I had
to pick just one I would go with the OIII. The H-beta is very specialized,
benefiting only a few objects. I don't have one.

I prefer the kind that screw into the eyepiece. That way I don't have to
remove the diagonal each time I want to switch filters.
