BRESSER 25x70 Binoculars for Astronomy |
SPECIAL ASTRO binoculars from BRESSER are ideal for astronomy and landscape observation.
Thanks to fully multi coated Bak-4 glass material and the extra large objective lens diameter these binoculars provide bright and high resolution images.
Due to the high 25x 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 in the lengthened centre axis, the SPECIAL ASTRO can be mounted onto any foto tripod. For tripod use you need the opional available tripod adapter (part No. 1916500). The use of a tripod is also highly recommended at a high magnification of 25x to obtain a steady image. |
