Product Description

Bresser Spezial-Astro 20x80 Porro Prism Binoculars

The Bresser Spezial Special Astro 20x80 Porro Prism Binoculars have fully multi coated Bak-4 optical glass. These binoculars have large 80mm/3.1" objective lenses which collect a large amount of light and produce vibrant images. 20x magnification is ideal for use for Astronomical observation binoculars, but these 20x80s can also be used for high power terrestrial viewing, such as birdwatching and nature spotting and aircraft identification.

These binoculars have a central mounting bar, with a 1/4" Whitworth-threaded mounting column, which can be attached to many suitable camera tripods - which are recommended for long-term use.
