Konus 20x80 Porro Binoculars for Astronomy

This beast is designed for astronomical and terrestrial viewing. The 20x80 Giant Binoculars from Konus features a very large 80mm objective lens with anti-reflection optical coatings to produce images that are brighter, clearer and more crisp than all others in the same category. This combination of objectives and coatings make them ideal for terrestrial observation, especially at low-light and astronomical stargazing too. The Giant bino by Konus comes with a high quality porro prism.

Since these binoculars are essentially two scopes mounted in tandem, it is recommended that they be mounted on a tripod. To help facilitate this, they come with a built-in tripod mount and center stabilizer rod. To help reduce the overall weight, the chassis is made of lightweight polycarbonate. An added advantage of this material is that it is more resistant to expansion and contraction with temperature changes than aluminum, which can cause the optics to shift out of collimation over time.
