2. TMB Supermonocentrics 10mm and 16mm
Both are in pristine condition. Come with original boxes. The 10mm was
bought
new from APM just last month and was never used - only been out of box
twice
for picture sessions.

There was a hilarious review of these in S&T, August 2004. (Those with poor
reading skills might not grasp the humor.)

Come to think of it, there _is_ one potentially funny thing about a monocentric
eyepiece.

Although it would be funnier if it were made of quartz instead of glass...

But the adjustments to your equatorial drive might be awkward...
