I have a pair of 1 1/4" eyepieces that came with an ST80 I purchased for use as a finder scope on a big Dob. One is a 9mm Kellner, the other is an RK 20mm complete with knurled grip. They are absolutely mint--haven't even been put in a diagonal. While they are generic, I am pleasantly surprised by their fit and finish. They look to be good starter eyepieces or options to use with "grabby fingers" at public star parties when you don't want to break out the Naglers. <g> Asking $10 each plus shipping.
