The MEP 20 - 60 Eyepiece is an accessory for Nikon Monarch 82ED and 60ED spotting scopes. This high-powered zoom eyepiece features Nikon's Field Flattener Lens System, which delivers consistent sharpness and clarity across the entire field of view. When mounted to one of the 82mm spotting scopes, the eyepiece has a 20 - 60x zoom range; on the 60mm scopes, the zoom range is 16 - 48x. A wide apparent viewing angle, 40.4 - 54.3° on either scope, provides immersive views throughout the zoom range. Its 16.1 - 15.3mm eye relief permits digiscoping, using the Monarchs' quality optics and large objective diameters as long camera lenses.
