Vintage Edmund Scientific RKE Eyepieces
Here is a complete set of vintage Edmund Scientific RKE eyepieces and the original case. Included are the 28mm, 21.5mm, 15mm, 12mm, and 8mm eyepieces plus the 2.5x barlow. These are the old style RKEs with adonized aluminum barrels. They are very well constructed oculars and have a very good reputation among many observers.
