Bresser 20 x 80 Astronomy Observation Porro Prism Binoculars
Brand New UK Stock, boxed with full Guarantee
The Bresser Special Astro 20 x 80 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 20 x 80’s 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.
