The 20x80 Cosmos Binocular from Barska has been designed for astronomical viewing and long distance terrestrial observation in low-light conditions. Boasting BAK4 Porro prisms and multicoated optics with a green lens, the large objectives maximize light transmission and image clarity. This Cosmos binocular features heavy-duty reinforced construction and includes an integrated tripod mounting post. Waterproof and fogproof, it has been constructed with an aluminum body to increase strength and reduce weight. Provisioned with an individual eyepiece focus system for fixed distance viewing; the celestial sights never looked so tantalizing.
