This is a TeleVue blem purchased at NEAF last month. If there's a defect, it's not in the optics; I can't find anything but minor cosmetics to explain the punch mark.
I got it as a modern alternative to a Speers-Waler 12mm, but there's no advantage except it's smaller, so I offer it for sale or trade as I'm duplicating eyepieces for a binoviewer.
I would be interested in trading for:
8.8mm Meade UWA
16mm Nagler 5
Thanks for looking
