Jason if your ED 80 is F6 you may have focus problems with certain eyepieces using a Solar wedge for WL . A barlow will generally help.As for Ha there are quite a few people here and we all use different make scopes and aperture sizes. As for aperture size for visual 60mm is good but many people use a PST and are happy with it. I am relatively new to this Ha so my opinion would be biased to what I have.Perhaps you can purchase a Coronado or Lunt Front filter with an adaptor for your 80mm and the appropriate rear blocking filter at a reasonable cost.
