Essentially a scaled-down version of the 8-element Type-2 design, the 6-element/4-group lens configuration employed in the Tele Vue Nagler Type-5 16mm Eyepiece was engineered to give those using telescopes with a 1.25" focuser a large true field and wide apparent angle of view — making it an eyepiece that is well suited for general observations on smaller OTAs or bino-viewers.
With a medium focal length, the optical properties allow it to maintain its wide 82° apparent field of view, and a comfortable 10mm eye relief. Built to Tele Vue's exacting standards, the Type-5 features anti-reflection fully multi-coated optics to improve brightness, color rendition, and contrast; and a fold-down rubber eyecup that helps to block stray peripheral light from interfering with the views and to further enhance contrast. A textured collar around the body ensures safe handling in the cold or while wearing gloves. The Type-5 has a barrel diameter of 1.25" to fit into the most common sized focusers and accessories, and is parfocal with all Tele Vue group 'B' eyepieces, allowing you to change eyepieces within the group without having to refocus every time.
