Do you have any oddball eyepieces. Rodenstock 40mm, Leitz 30mm 88°, a Pentax XL 60mm, Celestron Ultima 2" or ex-military/specialist? Or a ball eyepiece, ultra short or long focal length, radioactive (uranium, thorium, barium) glass, or hand made antiques?
Anything old &/or deviating from the norm these days, any converted from other equipment. The odder the better.
