The 20x80 binoculars have excellent color correction and edge-of-field sharpness due to their relatively long focal length. They offer extraordinary astronomical viewing, and are also great for long-range terrestrial observation - especially when viewing under low light conditions.
The giant 80mm objectives gather a great deal of light (30% more than 70mm objectives), yet contrast is excellent.
These binoculars include the finest BAK4 prisms and are fully broadband multi-coated. They have a long 18mm eye relief (unusual for such high-magnification binoculars), so can be used by those that wear glasses.
The binoculars feature light-weight rubber-armored 15" long body. They also include right ocular diopter adjustment, soft rubber ocular and objective covers, and a carrying case.
