No, I really don't! It's a 35mm Panoptic, which with a 20" f/5 gives about 72x. 
With an AFOV (apparent field of view) of 65 degrees on the Panoptic, this works 
out to about 54' actual field and 7mm exit pupil.

And, believe it or not, the views are ALWAYS both crisp and bright right to the 
edge of that field. I generally mistrust expensive astrogizmos (I respect AP 
and TeleVue refractors, but would NEVER buy one - and don't even get me started 
on Questar.) But there is a real good reason why TeleVue's Nagler and Panoptic 
oculars cost so much: they work! :)

Clear skies,
Lew
