Com'on Derek, that's not even a realistic consideration for his scope. It has a 36% greater focal length than what he is seeking and provides a "tiny" 8.4mm exit pupil in his F5 scope. It is a fine eyepiece in a slow F-Ratio scope, but not at F5.

Wren,

IMO you have chosen the right eyepiece in the 30mm Pentax XW for your 12"/F5 scope.

Cheers,
