Binger 20x80 astronomical binoculars telescope Fully multi coated BAK 4 prism focal length 520mm 1.25" helical focusers with U mount and wooden tripod

Binger DBL 20X80 is a smaller and lighter version of our highly-acclaimed SW25/40x100. It is the least expensive binocular on the market that offers 45°viewing and 1.25" focusers. And the 45° 80mm Binocular Telescope also has broadband multi-coatings on every lens surface, including the massive porro prisms. 20x fully multi-coated wide-angle eyepieces are included, but because of the industry-standard 1.25" helical focusers, your favorite telescope eyepieces can be used as well.
