Kowa TE-11WZ II 25-60x Wide Angle Zoom Eyepiece

Product Overview

The Kowa TE-11WZ II Wide Angle Zoom Eyepiece is a premium interchangeable eyepiece for Kowa's PROMINAR TSN-99, TSN-88, TSN-77 and TSN-66 spotting scopes. It delivers a 25–60x zoom range on the TSN-88/77/66 (and 30–70x on the larger TSN-99), with XD and field-flattener lens elements for true colour, edge-to-edge sharpness and a wide field across the entire zoom range. A twist-up eyecup provides generous, adjustable eye relief.
