I would like to trade this 2 inch Omcon Erfle for a Celestron (or Meade) F 6.3 Focal reducer. The FOV is 62 degrees according to the manufacturer. It is in good condition.
My preference is to work a deal in the Southern California area so that the actual exchange could be done in person. I live in San Diego, the closer the better.
My preference is also to trade the eyepiece but I would sell it as well.
