This item is in excellent condition. Lens surface shows no scuff/ no dust. Lens body shows no stain but there are some scratches on the pole and tripod mount part. Works Perfectly. Description This series of large nitrogen purged, waterproof binoculars stand alone in the field of combined performance and image quality. 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 starry sky or long distance terrestrial viewing. 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 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.
