Barska

Designed as an ideal optic for wide-view astronomical or long-range terrestrial observation, the Barska 20x80 WP Cosmos Astronomical Binoculars feature multicoated optics that reduce reflection and increase light transmission through the entire optical system, and traditional Porro prisms that provide a rich depth of view and high-contrast to draw you into an immersive viewing experience. To help offset the weight of the large objectives, Barska manufactured the chassis out of a durable aluminum alloy with a textured armor to help protect it from bumps and impacts while offering a slip-resistant grip. Due to the binoculars' large objectives and long optical tubes, a center stabilizer bar has been pre-installed with a built-in 1/4"-20 tripod adapter to mount the instrument. To handle a wide range of environments, the optical tubes are nitrogen-filled and O-ring sealed.Optical Performance Powerful 20x magnification allows you to make wide-field observations of the night sky, including the moon, constellations, and satellites, and long-distance terrestrial glassingOversized 80mm objective lenses draw in the light required to ensure views are bright and clearTraditional Porro prism optical path produces a rich depth of fieldBAK4 glass delivers a round exit pupil and a crisp and clear image with limited edge distortionAnti-reflection fully multicoated optics increase light transmission and contrast, and improves color renditionWide 60 apparent angle of view helps to minimize the appearance of distracting hand shake when holding high-power optics157-foot field of view at 1000 yardsUse and Handling Center stabilizer bar ensures the large optical tubes remain parallel without flexing under the weight of the objective lensesIntegrated 1/4"-20 tripod mount makes it easy to use with a support systemSliding mount enables proper balancing on tripod and headIndividual eyepiece focusing allows for precise tack-sharp viewsFold-down latex eyecups for use with or without eyewear15.4mm eye reliefComfortable 4mm exit pupilConstruction Details Lightweight and durable aluminum alloy chassisTextured rubber armoring provides a slip-resistant grip with impact protectionNitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging in extreme conditionsIncludes carrying case and lens cloth
