Product Details

  • 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 eyeguards deliver maximum contrast. Adapter skirts for 2 inch focusers on larger 1.25 inch models (12mm Nagler Type 4 and 22mm 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% full field visual inspection on our own flat-field test instruments guarantees the performance of every Tele Vue eyepiece.

    Televue Nagler Type 5 Eyepieces: 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 inch, 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.

    The 16mm Nagler Type 5 is a scaled down version of the "king of the field," 31mm. The 16mm is a smaller, lighter (0.45 lbs.), 1.25 inch only, 6-element design which replaces the 8-element 16mm Nagler Type 2. This exciting little high contrast eyepiece looks like a 19mm Panoptic, but packs the visual impact and sharpness we all expect from the 82 degree Nagler series. This eyepiece offers owners of 1.25 inch only scopes the largest possible true field in an 82 degree apparent field eyepiece. Great for small scopes and Bino Vues.
