68° Apparent Field Eyepieces
Housed in a 2" barrel like the 35mm, the 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! Standard on all Panoptics- multi-coatings
- blackened lens edges
- filter threads
- rubber grip rings
- cover for the eyeguard
- an undercut in the barrel for extra locking security
Al Nagler says of the Panoptics, "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."
