Tele Vue 35mm Panoptic

Description 68° Apparent Field Eyepieces The 35mm has a large true field with plenty of eye relief for eyeglass wearers.  When combined with a Paracorr to correct the coma of an f/4.5 Newtonian, performance is spectacular across the 68 degree field. Imagine, sharp star clusters at the extreme edge of the field along with a 6.8mm exit pupil! 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-35.0 Focal Length (mm) 35 Barrel Size (in.) 2" Apparent Field of View (deg.) 68 Eye Relief (mm) 24 Weight (lb / oz) 1.60 / 25.6 Field Stop (mm) 38.7
