Tele Vue 16mm Nagler Type 5 Eyepiece - 1.25" - EN5-16.0

The TeleVue 16mm Nagler Type 5 Eyepiece is a scaled down version of the "king of the field," 31mm TeleVue Telescope Eyepiece. The Type-5 16mm is a smaller, lighter (0.45 lbs.), 1.25" only, 6-element design which replaces the 8-element 16mm Nagler Type 2. This exciting little high contrast telescope eyepieces looks like a 19mm Panoptic, but packs the visual impact and sharpness we all expect from the 82 degree Nagler series. This telescope eyepieces offers owners of 1.25" only scopes the largest possible true field in an 82 degree apparent field TeleVue Telescope Eyepiece. Great for small telescopes and Bino Vues.

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 through the TeleVue 16mm Nagler Type 5 Eyepiece. 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
