Matthew, yeah, who would have thought from "such a simple question",
!
Wavy's brought up another point - the lack of information on the matching optical properties of different scopes vs those of eyepieces. Newtonians, Maks, refractors, SCT's, these have different properties inherent to them, to not even mention differences between f/ratios in each lot. Different EPs perform differently in each scope type. You will never read in a manufacturer's literature that a particular EP of their's performs poorly in any scope type. It's bull to think that any one EP will be as good in an f/3.7 Newt. as it will an f/15 Mak.
A new RKE which uses ED glass types? I'm in for using it in my fast Newts! 30mm to 5mm, 68 degree FOV, three elements, good eye relief, down to peanut sized, no astigmatism and deals with coma! Brilliant.
More like dreaming...
