TeleVue - 5mm Nagler Type 6 Eyepiece

Details

Nagler  5mm Type-6
 
82° Apparent Field Eyepiece

This new 5mm Nagler proves there is no need to sacrifice field in order to gain sharpness and power.   Lunar and planetary eyepieces with field to spare, the 7-element, Nagler Type 6 designs are based on the original patented Nagler design.  Using different exotic materials, coating processes and design ingenuity, more eye-relief, contrast, and true field of view has been incorporated into the shorter focal length Naglers while maintaining absolute sharpness.  The 5mm is, like all Type 6 eyepieces, parfocal and works great with the BinoVue.

Product Series

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

Nagler Type 4 Applying the experience of the Radian development to the 82° Nagler series, yielded more contrast, reduced pincushion, more true field, longer eye-relief, and fewer elements to achieve focal lengths of 12mm, 17mm and 22mm. With added eye-relief, the click-stop Instadjust eyeguard helps maintain proper eye distance and centration. For deep sky viewing, the comfort, clarity and contrast gets us closer to our "spacewalk" viewing goal. Nagler Type 5 With the 31mm, the unique 6-element design using four exotic glasses, maintains the contrast advancement of the Type 4s while achieving a true field area 82% larger than the 22mm Type 4! Owners of fast Dobsonian/Newtonians can enjoy a larger true field, free of secondary shadowing, than ever before. For example, a 12.5", f/4.5 scope with a Paracorr will deliver a 1.5 degree field (3 Moon diameters), at 53x with a 6mm exit pupil. Use our eyepiece calculator to figure out what the 31mm will deliver on your scope. Nagler Type 6 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. Available in 13mm, 11mm, 9mm, 7mm, 5mm, 3.5, and 2.5mm focal lengths.
