Vanguard Endeavor HD 82A Angled Eyepiece Spotting Scope with 20-60x Magnification The angled view Endeavor HD 20-60x82 Spotting Scope combines a nitrogen-filled magnesium housing and a fully multicoated optical path to create a well-equipped zoom optic for intermediate to long-range observation. Endeavor HD series features an extra-low dispersion (ED) lens system and phase-corrected BaK4 prisms, which maximize light transmission and produce color faithful images that are rich with contrast. This version of the Endeavor HD spotting scope includes a 20-60x zoom eyepiece featuring a rubber zoom dial. A 1:3 zoom ratio and 2.1-1.0° angle of view complement the eyepiece's long 19mm eye relief and rubber eyecup, which help to provide additional viewing comfort for long-duration observations. In addition to the image quality and weather-sealed construction, the Endeavor HD includes several features that enhance the scope's functionality. A stacked dual-focus mechanism enables the observer to make fine and coarse focus adjustments. The tripod mounting foot has a standard 1/4" socket and is compatible with Vanguard tripods that accept the universal mounting shoe. An integrated sunshade and included custom fit raincoat carrying case help to make the Endeavor HD a full-featured spotting scope for outdoor use.Optical Performance:- 20-60x magnification, 82mm objective- Extra-low dispersion glass elements, BaK4 prisms- Fully multicoated optics - 2.1-1.0° angle of view- 19.7 ft close focus distance (at 20x)Use and Handling - Angled view eyepiece is inclined 45° from the objective lens- Separate coarse / fine focus controls - Interchangeable eyepiece mount - Tripod mounting foot Construction Details - Nitrogen-filled fogproof / waterproof housing - Magnesium body with textured rubber armor - Built-in sunshield
