Don't know Gary, sometimes I think I can see down a single eyepiece with both eye's. As long as its a Panoptic of course.

As far as eyepieces go, after trying mine today, I think even some old orthoscopics, like those ones you carry around all the time, might do.
OCS???
Has anyone bought any of the GSO plossls that Andrews have for $39. If so what are their performance like, (internal reflections, sharpness to the edge etc) in an f/10 scope.
I'll certainly be doing some canvassing this weekend and at the Qld Astrofest Gary. Looking forward to the clouds and rain taking a holiday so I can make use of some new gear.
