Housed in a 2″ barrel like the 35mm, the Tele Vue Panoptic 27mm is lighter & smaller. It’s perfect for any telescope size, type or speed, where a little more magnification is desired, yet still allows full field viewing with eyeglasses. For example, with the Tele Vue-85, it gives 22x and a true field of 2.9 degrees!
68° Apparent Field Eyepieces
Concept: Using my Wide-Field design as a starting point, I looked to bring Nagler-like performance to the 60+° field class with the Panoptic series. The idea of a lens to “interface” between the eyepiece and Barlow struck me as the proper way to keep size, weight and cost to a minimum while improving edge of field performance even further. I later developed this idea into the Powermates. — Al Nagler
