Regular price 33,500.00


Designed for permanent mounting on a pier or porch, the binocular-telescope comes with a manual alt-azimuth fork mount. Capable of rotating a full 360°, it can tilt upward to 70° to view overhead or downward -30° if you're viewing land- or sea- based subjects from a balcony. To withstand the elements, the chassis is made from a durable and corrosion-resistant aluminum alloy, and the optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging in extreme conditions. The Nikon 20x120 III Binocular Telescope is a versatile and powerful optic for viewing terrestrial objects at extreme distances and enjoying wonders of the night sky such as the Moon, planets, comets, or some bright deep-sky objects like star clusters or galaxies. Optical Performance Powerful 20x magnification is ideal for extreme long-range terrestrial use, or for lunar and planetary viewing or wide-field comet hunting Large 120mm objective lenses help to offset the dimming that is common with high-power optics during the day and to draw in the light required for astronomy use Aberration-compensated lens system minimizes field curvature and color fringing for a flat and consistent field of view without distortion or astigmatism Anti-reflection fully multi-coated optics maximize light transmission for bright and clear images with accurate color rendition and improved contrast and clarity
