The Kowa TE-20H 25x Wide Angle Eyepiece for Kowa TSN-880 and TSN-770 series Spotting Scopes is one of the optional eyepieces designed to be used with your Kowa 88mm and Kowa 77mm spotters. Kowa's TSN-880 and TSN-770 series spotting scopes do not come with an eyepiece, and require an optional eyepieces for their operation.

Fully multi-coated optics provide a clear view, sharp image, and less distortion, while longer eye-relief than current eyepiece models allows eyeglass wearers to easily see the entire image. This unit has an eye relief of 32mm, as well as twist-up eyecup that can be set at different heights, allowing you to find the ideal viewing position (particularly good for eyeglass wearers).
