Thanks to fully multi coated Bak-4 glass material and the extra large objective lens diameter the BRESSER Spezial-Astro 20x80 Porro Binoculars provide bright, crisp images from edge to edge. Their high 20x magnification makes these excellent binoculars convenient not only for observing astronomical objects, but are also practical for viewing distant terrestrial targets and nature study. Their optical design and coatings minimise stray light and ghosting (even near brighter objects like the Moon), which would otherwise disrupt and detract from observing enjoyment.

Diopter compensation and foldable rubber eyecups give wearers of glasses the possibility of making the best use of these binocular's wide field of view.

With the tripod thread integrated in the strong central support column, which is adjustable along the centre axis bar, the BRESSER Spezial-Astro 20x80 Porro Binoculars can directly be mounted onto any suitable camera-style tripod and balanced front to back, once in place.
