For image quality and precise optics, Vixen's Giant ARK series of large nitrogen purged, waterproof binoculars are the answer. The same care that goes into making our high-end telescopes is evident in our large aperture binoculars.The Vixen ARK Series binoculars are used for viewing the night sky or for long distance terrestrial viewing. The 12x80 model has a 7mm exit pupil and 4.5 degree field of view is best suited for astronomical use.
The 80mm diameter lenses of these units 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 ARK series 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. Lens covers, tripod socket and hard carry case
