Barska 20x80 WP Cosmos Astronomical Binoculars (Black)
Key Features
  • BAK4 Porro Prisms
  • Anti-Reflection Multicoated Optics
  • Wide 60° Apparent Angle of View
  • Nitrogen-Filled, Water and Fogproof
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 glassing
  • Oversized 80mm objective lenses draw in the light required to ensure views are bright and clear
  • Traditional Porro prism optical path produces a rich depth of field
  • BAK4 glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  • Anti-reflection fully multicoated optics increase light transmission and contrast, and improves color rendition
  • Wide 60° apparent angle of view helps to minimize the appearance of distracting hand shake when holding high-power optics
  • 157-foot field of view at 1000 yards
