Kowa - 1.6x System S Eyepiece Extender

As part of their line of accessories, the Kowa 1.6x System S Eyepiece Extender is designed to increase the magnification of eyepieces without an appreciable loss of light—allowing you to see longer distances with greater details. Versatile and flexible, the System S series offers enhanced viewing solutions for all new and many discontinued Kowa spotting scopes.

The extender installs by screwing it onto the scope body. It has a bayonet mount to hold the eyepiece firmly and securely in place. Threads on the extender allow Kowa digiscoping adapters and other accessories to screw directly onto it. The extender fits old and new spotter models, although some may require an adapter ring or new eyepiece for a proper fit and use.
