Panoptic Eyepiece 19mm
Size, weight and performance make the 19mm an ideal mid power chioce. Ideal "soul-mate" to Bino Vue. Parfocal with 15mm and other smaller Plössls and Naglers.

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. — Al Nagler
