Designed as an ideal optic for wide-view astronomical or long-range terrestrial observation, the Barska 20x80 Cosmos WP Binocular features multi-coated optics to 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 users into an immersive viewing experience. This combination of optical coatings, prisms, over-sized objectives, and individually focusable eyepieces produce high-contrast views that are bright, clear and crisp, and tack-sharp.

To help offset the weight of the large objectives, Barska manufactured the chassis out of a durable aluminum alloy with a textured armoring on the outside to help protect from bumps and impacts while offering a slip-resistant grip. Due to the Cosmos' large objectives and long optical tubes it can feel fairly heavy with a center of gravity biased forward, so hand-holding it may cause fatigue and noticeable hand-shake. To facilitate putting it on stabilizing systems, its center stabilizer bar has a built-in 1/4"-20 tripod adapter to mount the instrument. To handle a wide range of environments, the optical tubes are O-ring sealed to be water and fogproof.
