16mm Konig. Used in vintage Quantum 6 telescope. Excellent condition. I don't have a picture available. This eyepiece was used in a Quantum 6 which was manufactured sometime in the late 70's. Very nice eyepiece. It looks quite different from the current version of Konig. The top of the eyepiece has a wide knurled edge. FOV is approx.
65 degrees. $60 including shipping in CONUS.
