Product Description

This is a superb short focal length ultra wide field eyepiece designed as an upgrade to the original and highly-prized 7mm Nagler. Due to the significant cost increase of this latest version over the original 7mm, the original 7mm Nagler will continue to be available for those who wish a lower cost alternative to competitive designs that are based on the original Nagler optical formulation.

This 1.25" eyepiece uses seven optical elements for optimized performance across a very wide field of view. Several different extra low dispersion glass types and specialized coatings are employed for improved contrast and longer eye relief than previous Nagler designs, even those acclaimed as being among the finest wide field eyepieces available. At a usable eye relief of 12mm, the 7mm Nagler would normally vignette the field of view for eyeglass wearers. However, since the 82° field is so wide that you can't see the full field without having to move your head from side to side to take it all in anyway, vignetting in the conventional sense is not a problem.

The optical performance is typical TeleVue - well corrected and sharp from edge to edge. There is a slight loss of contrast when compared to an eyepiece with fewer elements, due to the additional lenses needed to achieve the unique combination of very short focal length and very wide field. The loss is minimal though, on a par with the contrast loss in an eyepiece/Barlow combination with the same effective focal length. In the eyes of many observers, however, the "picture window on space" observing experience of its exceptionally wide field more than makes up for any slight contrast loss.

Supplied plastic caps seal both ends of the eyepiece to keep it dust free. A rubber grip ring gives a secure and comfortable grip in all temperature extremes. A groove machined into the chrome barrel of the eyepiece acts as a safety stop to keep the eyepiece secure should the focuser thumbscrew loosen slightly while using the eyepiece.

Along with the other two eyepieces in this series that I own (TV 13mm and 7mm T6), this one is an outstanding performer that lives up to its brand’s reputation. Very well corrected and comfortable even for eye glass wearers. Highly recommended. (Posted on 10/28/2019)

If you're looking at this eyepiece, you probably already know it's reputation. Sharp edge to edge with my 4 inch f/6.5 ED refractor and 6 inch F8 achro. There are wider FOV eyepieces today, but this still delivers that porthole to space experience. The eye relief is good without glasses - never tried with glasses. It's a keeper! (Posted on 7/23/2019)

This is the eyepiece I use for high power observations, there is no kidney beaning effect, it is sharp end to end. I use it to star test and split doubles, and when conditions permit planetary viewing. I need eye relief and the 7mm Televue Nagler is every comfortable. If I had to pick one of five eyepieces to have, this would be one of them. (Posted on 1/14/2019)

This is one of two Type 6 Naglers I own, the other being the 13mm. The 13mm Nagler has a well-deserved reputation of its own, but the 7mm is nearly as good, albeit a bit darker because of the higher magnification it produces. To me, the 13 has a bit better light transmission, but that may be an effect of my using a small scope. Like the 13, the 7mm Nagler packs a huge field of view into a small package. This is a great high power eyepiece - stick on a 2x Barlow or Powermate and you’ve got yourself a 3.5mm Nagler as well! The 12mm eye relief is great for a short focal length eyepiece, but may be a bit tight for some. If you need glasses, a comparable focal length Delos or DeLite would be a better option.

This was my first 82º eyepiece. I was hooked. The views are spectacular and sharp to the edge. A bit tight for eyeglasses though. (Posted on 12/10/2018)
