6mm Intes-Micro Monocentric triplet eyepiece.
This is a highly specialized eyepiece for planets and globular clusters. It's desiged for maximum light throughput, and has the absolute minimum of air-glass surfaces - two! Bright, very good polish, very sharp.

- Russian heavy-handed multi-coatings (would be better off without them) result in "green ghosts". My other triplet ep's aren't coated and don't have ghosts at all... go figure!
- Very narrow 30 degree field of view. Must be used in a driven scope. No "spacewalk" here! You will be amazed at how narrow this field is! Of course, this makes no difference when observing planets with a driven scope.
- Minor scuffs on top of EP (see pic). Glass is as new. Minor irregularity around field stop (from factory).
- Does not work well in scopes f6 or faster, but does barlow well.

As I said, this is a specialty eyepiece, and not for everyone. If you are looking for maximum light throughput from your f12 planetary newt or refractor on a GEM mount, this might be worth a try.

Looking to get $50 ppd in CONUS, trade for 32mm Plossl, or partial trade for old style 7mm Nagler. Will consider other "interesting" offers.
