Bresser Astro 20x80 binoculars are astronomical binoculars with significant characteristics. The large diameter of the lens picks up 30% more light, lower than the 70 mm model, and allows you to view the stars of weak light (up to 11.6 magnitudes), which is not accessible to any amateur telescope. In a stable atmosphere, the binoculars allow you to observe the new acquisitions from the planet Perseus, the Andromeda galaxy, without even mentioning the Earth’s satellite – the Moon. This device does not have polarity or other complex adjustments, which makes it ideal for simple astronomy without limitation. It is not possible to ignore the above-ground cautions: the level of detailing is such that it does not disappoint the owner of his device.
The compact, shock-resistant body of the binoculars has a hermetically sealed design that prevents the penetration of moisture and the formation of condensation on the internal optical surfaces. The specially abrasion-resistant, anti-bleeding, high-glossy green coating of semi-apochromatic lenses protects against smudges and maximizes light penetration. Prisms made from high-acidity, low-dispersion optical glass BAK4 allow you to capture the most accurate and contrasting image on the eyepiece.
The binoculars are equipped with an adapter for mounting on a tripod. A high-quality tripod is necessary to capture the extremely small microscopic lenses of the binoculars, which produce images at 20x magnification. Covers for eyepieces and lenses, a soft case and a strap allow you to protect the binoculars from damage during transportation.
