SPEZIAL 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.
The high
25x magnification it is convenient not only for observing
astronomical objects, but is also practical for viewing distant terrestrial objects too. Due to a very high reduction of stray light, by multi coating all air to glass surfaces, the binoculars deliver the best possible performance and excellent contrast.
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
SPEZIAL ASTRO can be mounted onto any photographic tripod. For tripod use you need the optional available tripod adapter (part No. 4914925). The use of a tripod is highly recommended with these binoculars, as at the high magnification of 25x it's difficult to maintain a steady image by hand holding (though this is possible for short periods).
