Here's a great eyepiece. Views are crisp and clear and oh so contrasty. Other than a couple of set screw marks, the eyepice is in excellent shape. I have all the original paperwork. Why buy a set of wide field eyepieces when this one will do? I am asking $300 or am willing to trade for a used (but in good shape) Panoptic 35 or Panoptic 27.
