Re: Ad #87070 - Previous ad for a Pretoria EP is in error . . . it's a 28mm, not a 20mm (sorry).
Accordingly, I am selling my University Optics 28mm Pretoria eyepiece; 2" wide-field with fully multi-coated optics, and an integral coma corrector. This is UO's most unusual and most coveted eyepiece - no longer produced, and used ones are rarely seen offered for sale. EP is in excellent condition, however the usual barrel marks are present, there's no box, and I can't promise original caps. Because it's difficult to establish a current market price for this unusual eyepiece, I will consider all legitimate offers, including interesting trades. Thanks . . .
