The Tele Vue 7mm Type 6 Nagler eyepiece design is based on the original patented 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, TeleVue 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 Type 6 model, and all are sized about the same as the original 7mm!
All Tele Vue Nagler eyepieces have proprietary tuned full multi-coatings, blackened lens edges, high index glasses, fold-down eyeguards, rubber grip rings, cover for the eyeguard, an undercut in the barrel for extra locking security, and filter threads. All Tele Vue eyepiece lines are proprietary, in-house designs manufactured to their specifications and tolerances. Every eyepiece is individually tested at Tele Vue to ensure it meets high optical and cosmetic standards.
Take a "spacewalk" across a wide, sharp 82° apparent field
Compare a penny to a half dollar to see the relative size between a 50° and 82° apparent field - almost 3 times the area difference! And while others 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. Blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast. Adapter skirts for 2" focusers on larger 1¼" models and rubber grip rings are additional Tele Vue "firsts". Even 2"/1¼" barrel models have an additional feature allowing the 2" extension tube (EBX-2120, sold separately) to be screwed on, which permits use of 2" filters as well as 1¼". 100% full field visual inspection on TeleVue's flat-field test instruments guarantees the performance of every Tele Vue eyepiece.
Concept: "You may know there's a long history of naming 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 "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
The Type-5 permits the largest true field possible (31mm has 42mm field stop), while the shorter focal length Type-6 models are parfocal, with similiar size and weight and all with a comfortable 12mm eye relief.
The Type-4 models feature about 18mm of eye relief and with the "instajust" eyeguard are best for eyeglass wearers or Dioptrx users in their 22, 17, 12mmfocal length range.

Nagler type 6Pros: Cons: Comments:
This is the ideal eyepiece I've imagined for medium to high power which makes use of the flat field of my fast 6" Explore Mak-Newt to give an image of remarkable undistorted clarity all the way across.

Everyone Should Have This EyepiecePros:
High power wide views; Lighter than other “Type” Naglers; Great qualityCons:
Price, Eye relief @ 12mm might be too short for eyeglass wearersComments:
I use this one every time I go out. This is a great eyepiece, as all Naglers are. It offers high contrast and sharpness edge-to-edge. This is my standard planetary eyepiece. No matter what the sky is doing, this will pull the best view. With the 82 degree field of view, you can see the moons around Saturn and Jupiter all in the same high power view. But the best thing about this Nagler Type 6 is its size and weight! At only ½ pound most any scope can take advantage of what it can do.Sort by
