DESCRIPTION

Tele Vue 9mm Nagler Type 6 Eyepiece

This 1.25-Inch Tele Vue 9 mm Nagler Type 6 Eyepiece is part of the great Nagler Series

 

Tele Vue Nagler Eyepieces:

"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 '70s 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 


Compare a penny to a half dollar to see the relative size between a 50-degree and 82-degree apparent field - almost 3 times the area difference! And while others boast of impressive apparent field sizes, Tele Vue's philosophy of "showing no field unless it's fine" stresses full field image quality as the ingredient for impressive views. Blackened lens edges, anti-reflection threads and rubber eye guards deliver maximum contrast. Adapter skirts for 2-inch focusers on larger 1.25-inch models (12 mm Nagler Type 4 and 22 mm Panoptic) and rubber grip rings are additional Tele Vue firsts. Even 2-inch/1.25-inch barrel models have an additional feature allowing the 2-inch extension tube (EBX-2120) to be screwed on, which permits use of 2-inch filters as well as 1.25-inch. 100-percent full field visual inspection on our own flat-field test instruments guarantees the performance of every Tele Vue eyepiece.

Tele Vue Nagler Type 6 Eyepieces: 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 12 mm on each model, and all are sized about the same as the original 7 mm! Weight about 0.4 to 0.5-pounds.

Tele Vue Note: 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. We are confident we've succeeded on all accounts and look forward to your comments.

This is about the only eyepiece I use anymore. I just love it. It gives wide open sharp views with good contrast. Well worth saving for!
