Tele Vue 27mm Panoptic

Description 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."   Specifications Model # EPO-27.0 Focal Length (mm) 27 Barrel Size (in.) 2" Apparent Field of View (deg.) 68 Eye Relief (mm) 19 Weight (lb / oz) 1.03 / 16.4 Field Stop (mm) 30.5
