Nikon 24x/30x Wide DS Eyepiece

The Nikon 24x/30x Wide DS Eyepiece is a premium quality wide angle eyepiece. It's designed to fit the same body of Nikon Fieldscope Spotting Scopes as the standard 24x eyepiece, but provides a wider field of view.

The wide field of view, combined with the excellent optical quality of this eyepiece, makes it ideal for viewing objects closer to the horizon. It offers a 72° apparent field of view and 16x magnification with the 50mm scope, 24x with the 60mm scope, and 30x with the 82mm scope.

This premium product is waterproof, fogproof and nitrogen purged to prevent internal fogging and moisture build-up during long periods of storage or use in damp conditions.
