The TE-11WZ Prominar 25-60x Zoom Eyepiece from Kowa is a weather-resistant spotting scope accessory designed to complement the optical excellence of Prominar series scopes. This high-powered zoom eyepiece features Kowa's extra-low dispersion (XD) glass elements, which transmit color faithful images with enhanced contrast and sharpness. When mounted to one of the 770 or 880 spotting scopes, the TE-11WZ has a 25-60x zoom range; on the 500mm f/5.6 Photoscope, the zoom range is 28-66x. A wide apparent viewing angle, 60-79° on the 770 or 880 scope, provides immersive views throughout the zoom range. Additionally, the eyepiece's long 17mm eye relief is constant at any magnification setting, providing a comfortable viewing distance even at maximum power.
