TeleVue 3.5mm Nagler Type 6

5.0 out of 5 stars
1 customer reviews


The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. You don't have to sacrifice field in order to gain sharpness and power. And, you're not limited to slow scopes, or have to squint through pinhead lenses. This is a lunar and "planetary" eyepieces with field to spare.

The 7-element, Nagler Type 6 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, 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 model, and all are sized about the same as the original 7mm! Weight about 0.4 to 0.5 lbs.

Concept: The goal we set designing these new eyepieces was to increase contrast, maintain or increase eye-relief, reduce size and weight, and maintain the sharpness of the originals. They are all parfocal and great with the Bino Vue.

Why Are There 3 Types of Naglers?

To achieve the full magnification range over 82° apparent field of view requires two types: Nagler Type-5 with focal lengths of 31, 26, 20, 16mm and Nagler Type-6 with focal lengths of 13, 11, 9, 7, 5, 3.5, 2.5mm.

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, 12mm focal length range.

Warming up to the Nagler

By PETER HAZZARD on October, 17th 2009

I wasnt very impressed with this eyepiece at first! After looking through Radians for the past 4 years, I have gotten used to seeing the entire 60 degree field at once. With the type 6 Naglers i have to move my face and peer around the corner to see the edge.The Radians seem slightly sharper and seemed to have less glare. However with continued use and some clear nights i am beginning to like this eyepiece. On the moon you get a wide field and since the eye is closer to the glass, a closer more intimate view. If the moon has a halo from moisture or haze, the glare will be more bothersome than the Radians. If the air is clear and dry the view is great.
