The 20x80 "Standard" binocular has excellent color correction and edge-of-field sharpness due to its relatively long focal length. Offers extraordinary astronomical viewing, and is also a great choice 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), and contrast is excellent. Includes the finest BAK4 prisms and is fully broadband multi-coated. It has a long 18mm eye relief (unusual for such a high-magnification binocular), so they can be used comfortably by those who wear glasses. Light-weight rubber-armored 15" long body. Also includes right ocular diopter adjustment, soft rubber ocular and objective covers, and a carrying case.
