Eyepieces for H-alpha telescopes

[Terry Byatt]

Considering the extremley narrow band pass of H-alpha telescopes, is there any point in spending a lot of money on highly corrected eyepieces? Would not  simple Kellners be adequate?

From a chromatic aberration point of view probably not – but many prefer wider fields of view, and ‘better’ eyepieces may be better constructed, with better coatings.

I usually use my TV plossls on my Lunt solar scope – i quite like the combination.

Zoom eyepieces seem to be quite popular too, though I don’t have one.
