Tele Vue 3.5mm Nagler Type 6 Eyepiece - 1.25" - EN6-03.5

The 7-element, TeleVue 3.5mm Nagler Type 6 Eyepiece design is based on the original patented TeleVue Telescope Eyepiece Nagler design. This new 7-element design update for the short focal length Nagler deserves its own designation. Using different exotic materials, coating processes and design ingenuity, Al has massaged more eye-relief, contrast, and true field of view into the shorter focal length Naglers, while maintaining the absolute sharpness of the originals. Eye-relief is 12mm on each TeleVue Telescope Eyepiece model, and all are sized about the same as the original 7mm! Weight about 0.4 to 0.5 lbs.

Compare a penny to a half dollar to see the relative size between a 50 degree and 82 degree apparent field - almost 3 times the area difference! And while other telescope eyepieces boast of impressive apparent field sizes, Tele Vue'''s philosophy of "showing no field unless it'''s fine" stresses full field image quality as the ingredient for impressive views. The TeleVue 3.5mm Nagler Type 6 Eyepiece features blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast. Adapter skirts for 2" focusers on larger 1.25" TeleVue Telescope Eyepiece models and rubber grip rings are additional Tele Vue "firsts". Even 2"/1.25" barrel models have an additional feature allowing the 2" extension tube (EBX-2120) to be screwed on, which permits use of 2" TeleVue Eyepiece Filters as well as 1.25". 100% full field visual inspection on TeleVue'''s own flat-field test instruments guarantees the performance of every TeleVue Telescope Eyepiece.

"You may know there'''s a long history of naming telescope eyepieces after their designers: Kellner, Erfle and Plossl, to name a few. In the late 70'''s I designed an eyepiece sufficiently radical that I dared attach my name to it. Even today, I must admit a little discomfort when talking about "Nagler" eyepieces.

With TeleVue Telescope Eyepiece "Naglers", my aim is to approach the wide angle perspective of naked eye vision, while maintaining the highest degree of sharpness, contrast, and viewing comfort. The goal is to allow the telescope to virtually "disappear," leaving the impact of "spacewalk" viewing." --Al Nagler
