Tele Vue Nagler Type 5 Eyepieces

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.

The 16mm Nagler Type 5 is a scaled down version of the "king of the field," 31mm. The new 16mm is a smaller, lighter (0.45 lbs.), 1¼” 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° Nagler series. This eyepiece offers owners of 1¼" only scopes the largest possible true field in an 82°apparent field eyepiece. Great for small scopes and Bino Vues.

26mm Nagler Type 5: This is a somewhat smaller, lighter and more powerful version of the celebrated 31 Nagler Type 5. Why? Because customers such as Tom Dietz, from the Smithsonian, are pests! :-) It weighs about 1.6 lbs and has a field stop diameter of 35mm. It is parfocal with the 17mm Nagler Type 4, making it a nice match in size, weight and convenience.

The 20mm Type 5 is a compact 1-pound, 2" eyepiece that fills out the eyepiece line and is a worthy successor to the heaviest commercial eyepiece ever produced: the Nagler 20mm Type 2, wich weighed-in at 2.3lb. when introduced in 1986.
