The straight view Endeavor HD 15-45x65 Spotting Scope from Vanguard 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. Vanguard gave the Endeavor HD series 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 15-45x zoom eyepiece featuring a rubber zoom dial. A 1:3 zoom ratio and 2.7-1.3° 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.
