I have a research grade 20mm erle eyepice I bought many years ago from an ad in Astronomy magazine. This has similar AFOV as a Panoptic but obviously not the same edge sharpness. It works well on a slow SCT or Mak though. Comes with a nice eye shade that blocks stray light and plastic case. Priced to sell. $30.00 and I'll pay postage.
Thanks for looking.
