  • Description

    Tele Vue Nagler Type 5 eyepieces include the 16mm, 20mm, 26mm and 31mm focal lengths.  "Naglers" are a run-away favorite with amateur astronomers all over the world. With a large 82 degree field of view, great eye relief, and amazingly sharp optics, it is no wonder that Al Nagler's "Space Walk" eyepieces are some of the most coveted telescope accessories of all time.

    To see the relative size difference between a 50 degree and an 82 degree eyepiece, lay a penny and a half dollar down on the table side by side. The difference is huge—the half dollar has almost three times the area of the penny! Al Nagler wanted to give his customers an experience that would be similar to looking at an object with the naked eye—except with lots more magnification!— and the 82 degree Nagler’s definitely hit the mark. After awhile, you will forget that you’re looking through an eyepiece at all, and you’ll feel fully immersed in the experience.

    All Nagler eyepieces have blackened lens edges, anti-reflection threads and rubber eye guards for maximum contrast. Innovative features, such as adapter skirts for 2” focusers on larger 1.25” models and rubber grip rings were invented by Tele Vue. Even the 2” to 1-1/4” barrel models have an additional feature allowing the addition of a 2” extension tube (EBX-2120), which permits the use of 2" and 1.25” filters. A 100% full field visual inspection on Tele Vue’s flat-field test instruments guarantees the performance of every Nagler eyepiece.

    Type 5 Nagler Eyepieces

    Tele Vue Nagler Type 5 eyepieces have focal lengths in the low to medium magnification range.  Al Nagler designed Type 5 eyepieces to offer the largest true field possible in an 82 degree apparent field eyepiece. A standard rubber eyecup is included, and most of the Type 5 eyepieces have enough eye relief to be Dioptrx compatible, allowing you to correct for near- or far-sightedness while at the eyepiece.

Customer Q&A

1 - 5 of 12

  • Q1: I am not sure which Televue eyepiece series to purchase, Nagler, Panoptic or Radian. I wear glasses occasionally for distance, but not for viewing through binoculars. I will be buying my first telescope from you shortly and am planning to buy either the Meade LX200GPS 10, 12 or 14" with UHTC. I want to decide how much money I am willing to spend first. I will want a set of Televue eyepieces for my new scope due to the excellent reputation and reviews I have read. This will be my first telescope. I notice the Naglers have the widest field of view and the shortest eye relief. I assume the Radian have the narrowest field of view with the longest eye relief. Any suggestions?

    A: If this is your first scope I suggest going with the Nagler. Even though they will have the shortest eye relief the extra wide field of view will come in very handy as you are trying to learn how to use your scope. The easiest way to say it is that the wider the field of view the more forgiving it is when aligning on very distant objects.

  • Q2: These eyepieces would work with my Celestron AstroMaster 70, correct?

    A: Yes the 1.25" TeleVue Nagler Telescope Eyepieces will work with a Celestron AstroMaster 70.
