Tele Vue 2" 20mm Nagler Type 2 Telescope Eyepiece. Great condition. Please be aware that this is a substantial piece of glass--36.8 oz.(2.3 lbs)-- about an ounce heavier than the current heavyweight champion, the Nagler 31mm Type 5. May not balance in lighter scopes. If it does, the views are incredible.
Manufacturer specs: apparent field of view 82 deg, field stop 27.4 mm, eye relief 12 mm.
Hate to let this one go, but it's just too much eyepiece for the portable telescope that I use most often.
