You can use the Bresser Spezial-Astro 20x80 binoculars to observe celestial objects, thanks to the 20x magnification. Focusing starts at 30 meters. The lens has an 80-millimeter diameter, which means a lot of light will fall through the lens. The lenses are made of BAK 4 glass and feature multi-coating. This provides contrast-rich images. Using the integrated tripod adapter, you can easily mount the binoculars onto a tripod. Thanks to the eyeshades that swivel, you can adjust the binoculars to your eyesight.Note! At a magnification level of 12x or higher, you'll need a tripod to see stable images.
