This eyepiece is 6 mos. old with box and papers. I used it a few times with my GPS 11 and the original diag. so it has about 3 small pressure marks from the set screw. (I now have a 2" Astro Physics diag. w/brass rings) Asking $210 in money order/bank check and I will pay for all shipping and insurance in USA. For foerign orders just let me get the added cost and add it to the eyepiece.
For pick-Ups I'm in the Boston MA area.
