5.7mm eye piece(s)?Posted By John MacDonough |
Could the Stellafane folks be asking for an eye piece like that so that all entrants have an eye piece that gives a 1mm exit pupil so there is some common ground during judging?
A 5mm or 6mm ortho...
A 5mm or 6mm Plossl...
An old Orion Epic ED-2 5.1mm (blacks out easily, but only $35 if you find one used)
Meade 5.5mm UWA
I'm pretty sure Explore Scientific makes a 5.5mm eye piece, too
Tele Vue 5mm Radian
Tele Vue 5mm Nagler
