     German binoculars Bresser provide the highest quality optics combined with ergonomic modern design. Many developments used in the manufacture of these devices are unique and protected by patents.

     All binoculars of the Spezial series are individual and designed for different purposes. BRESSER SPEZIAL - ASTRO 20 x 80 is an astronomical binocular with outstanding characteristics. The large diameter of the objective collects 30% more light than 70 mm models and allows you to observe faint stars (up to 11.6 stellar magnitudes), which is not available to every amateur telescope. In a stable atmosphere, the binoculars will allow you to observe the double cluster in the constellation Perseus, the Andromeda galaxy, not to mention the Earth's satellite - the Moon. This device does not provide polar alignment or other complex settings, which makes it ideal for simple astronomy without restrictions. But do not ignore terrestrial observations: the level of detail is such that it will not disappoint the owner of this device.

     The rubberized, shock-resistant body of the binoculars has a hermetically sealed design that prevents moisture penetration and condensation on the internal optical surfaces. A special abrasion-resistant, anti-glare, multi-layer enlightened green coating of the semi-apochromatic lenses protects against scratches and promotes maximum light penetration. The prisms are made of  high-quality low-dispersion optical glass BAK 4 and allow you to get the most accurate and contrasting picture on the eyepiece.

     The tripod and adapter are included in the kit and will help to avoid unwanted micro-movements of the binoculars, which distort the picture at 20x magnification. Covers for the eyepieces and lens, a soft case and a strap will help to protect the binoculars from external damage during transportation.
