The ASTRO & MARINE binoculars from BRESSER are ideal for astronomy and maritime use, e.g. sailing and water sports enthusiasts.
Thanks to their ergonomic rubber armouring, these binoculars fit securely in the hand and are also well protected against shocks and bumps. The binoculars are waterproof and filled with nitrogen. This effectively prevents fogging of the lenses, even in unfavourable weather conditions.
The robust, yet very light construction is made possible by the most modern magnesium housing construction. Magnesium is around 35% lighter than aluminium. Due to the moderate 7x magnification and the low weight, these 7x50s are also very well suited for hands-free use. Nevertheless, there is a tripod connection thread on the centre axis. This means that the ASTRO & MARINE model can also be mounted securely on a photo tripod using the tripod adapter (Art.4914925) which is included as part of the package. Although this is not absolutely necessary with a magnification of 7x, it is highly recommended, especially for long-time astronomical observations, in order to obtain an absolutely steady image.
The precise single eyepiece focusing (SF) makes it possible to focus the binoculars once and then clearly observe all resolvable objects in the night sky, or on the horizon. In addition, this design prevents accidental change of focus. Foldable rubber eyecups and eyepieces with a comfortable eye relief distance (WP) of 20mm also allow those who have to wear glasses to observe, to use the entire field of view.
Thanks to fully multi-coated Bak4 optics, large 50mm objective lens diameter and the well-corrected eyepieces with 3 lenses in 2 groups, these excellent binoculars produce sharp and brilliant images. The maximum reduction of stray light achieved by internal baffles and housing/edge blackening, results in the best possible optical image and perfect contrast, even in difficult light conditions and especially at night.
