Based on the original Nagler design, the 7-element/4-group lens configuration employed in the Tele Vue Nagler Type-6 13mm 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 excellent 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 colder weather, if you might be wearing gloves.
