About the TeleVue 35mm Panoptic Eyepiece - 2"... The TeleVue 35mm Panoptic Eyepiece has a large true field with plenty of eye relief for eyeglass wearers. When combined with a TeleVue 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! "Using my Wide-Field TeleVue Telescope Eyepiece design as a starting point, I looked to bring Nagler-like performance to the 60+ degree field class with the Panoptic series. The idea of a lens to "interface" between the TeleVue Telescope Eyepiece and TeleVue Barlow Lens 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 TeleVue Powermate." --Al Nagler Be sure to check out our line of TeleVue Telescopes, TeleVue Telescope Mounts and TeleVue Telescope Accessories.
