Tele Vue 41mm Panoptic

Description 68° Apparent Field Eyepieces The 41mm Panoptic eyepiece is a big brother to the 24mm Panoptic (largest 1.25" field). With its 46mm field stop, the 41mm Panoptic delivers the largest 2" field possible. An adjustable and removable screw-type top allows quick, comfortable eye positioning. The scalloped shape gives a positive grip. 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-41.0 Focal Length (mm) 41 Barrel Size (in.) 2" Apparent Field of View (deg.) 68 Eye Relief (mm) 27 Weight (lb / oz) 2.10 / 33.6 Field Stop (mm) 46
