Thanks to fully multi coated Bak-4 glass material and the extra large objective lens diameter these binoculars provide bright, crisp images from edge to edge.
Due to the high 20x magnification it is convenient not only for observing astronomical objects but is also practical for viewing distant terrestrial objects. Due to a very high reduction of stray light, the binoculars deliver the best possible picture and a perfect sight.

Diopter compensation and foldable rubber eyecups give eye glass wearers the possibility of making the best use of these optics’ field of view. 
With the tripod thread integrated in the lengthened centre axis, the ASTRO can directly be mounted onto a tripod.
