Since I'm used to using mostly 2" dia. eyepieces for observing with my larger scopes, what eyepieces might I use with a C8, especially for lowest power observing?

Wider than this and the very edge of the field will loose faint stars. But that only matters if it matters to you.

A TV 35 Pan has a 38.7MM field stop, yet I doubt you would notice the slight narrowing of the field of view. My speadsheet shows you'll have a tad over a full degree field of view at 58X with this EP.
