Nikon 20-60X Edg Fieldscope Eyepiece 8299

The 16-48x/20-60x Zoom Fieldscope Eyepiece from Nikon is a nitrogen-filled fully multicoated zoom eyepiece ideal for bird watching, terrain navigation, and digiscoping. Place this eyepiece on your fieldscope to zoom the range of focal lengths. When attached to an EDG series fieldscope, magnify the focal length of your optics by 20x-60x.

The Zoom Eyepiece delivers bright vivid images, broad viewing angle, and is effective for use in low-light conditions such as dusk and dawn. Aspherical lens elements correct image distortion, providing a vivid flat image even at both extremes of the magnification range.
