Based on the original Nagler design, the 7-element/4-group lens configuration employed in the Tele Vue Nagler Type-6 9mm Eyepiece was designed as an ideal eyepiece for lunar and planetary viewing.
Despite its medium focal length, the optical properties allow it to maintain its wide 82° apparent field of view, and a comfortable 12mm eye relief that provides space between the lens and eye to prevent accidental contact that can interfere with views. Built to Tele Vue's exacting standards, the Type-6 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 ensure safe handling in the cold or while wearing gloves. The Type-6 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.
