|This series of large nitrogen purged, waterproof binoculars - the Vixen Giant ARK Astronomy Binoculars - stand alone in the field of combined performance and image quality. The same care that goes into making Vixen''s high-end telescopes is evident in their large aperture binoculars. All binoculars can be either hand held, or for the most stable viewing platform, mounted on our Porta mount or a photographic tripod (with the optional tripod adapter).
The large aperture lenses of these Vixen Giant ARK Astronomy Binoculars allow the observer to take in such celestial sights as the Orion or Lagoon Nebula and other celestial wonders. The Milky Way, the Moon and bright comets will jump out at you with this combined aperture and power.
The optics on the Vixen Giant ARK Astronomy Binoculars are multicoated and the prisms are made from BaK4 glass. This combination allows for the greatest transfer of light through the optics. Other benefits include rugged optical housings, fine focusing and a right eye dioptor to allow for left/right eyesight differences.
