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?

Eyepieces for H-alpha telescopes
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.
