TeleVue Nagler Eyepiece

The TeleVue Nagler Eyepiece Comes In 3 Different Types

To realize the full magnification range over 82° apparent field of view requires 2 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 TeleVue Nagler Type-5 allows for the largest true field achievable (31mm has 42mm field stop), while the shorter focal length Type-6 models are parfocal, with similiar weight and size and all with a more comfortable 12mm eye relief.

The Type-4 models feature approximately 18mm of eye relief and with the "instajust" eyeguard are ideal for eyeglass wearers or Dioptrx users in their 22, 17, 12mm focal length range.

Nagler Type 6

The 7-element, Nagler Type 6 design shown below is founded on the original patented Nagler design. This new 7-element design update for the short focal length Nagler warrants its very own designation. Making use of diverse exotic materials, coating processes and design resourcefulness.

More eye-relief, contrast, and true field of view has been massaged into the shorter focal length Naglers, while still 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 approximately 0.4 to 0.5 lbs.
