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."
