Tele Vue Nagler Type-6 13mm Eyepiece (1.25')

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 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.
