I have a hardly used 40mm TMB Orthoscopic superwide eyepiece in newish condition. It has the box, it looks new, I may be able to find lens caps but currently they are not with it in the box. This is a 2 inch eyepiece and compares favourably with the famous (and expensive) Televue 41mm Panoptic:

AUD$250 + postage (should only be $10) within Australia.
Selling as I primarily do imaging and want to fund a camera lens.
