Televue 35mm Panoptic Eyepiece. 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 exist pupil!
Concept: Using my Wide-Field 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 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.
