Levenhuk Bruno BASE 20x80 Binoculars (85536)

The Levenhuk Bruno BASE 20x80 binoculars are designed for powerful long-distance observation, making them suitable for astronomy and terrestrial viewing alike. With 20× magnification, they allow detailed observation of lunar craters, Jupiter’s moons, and bright nebulae, while also performing well for distant landscapes and land-based targets.

Powerful Optics for Low-Light Observation

The large 80 mm objective lenses provide strong light-gathering capability, making these binoculars effective in twilight or moderate lighting conditions. The optical system features fully multi-coated elements, including BaK-4 Porro prisms and high-quality lenses. This configuration ensures excellent light transmission, high contrast, and minimal edge distortion.

A 4 mm exit pupil supports comfortable viewing during dawn or dusk. Diopter adjustment of ±4 diopters compensates for differences between the eyes, while smooth central focusing allows quick and precise adjustment.

Durable and Weather-Resistant Design

The body is constructed from aluminum alloy and covered with a rubber coating for a secure grip and added shock protection. With an IPX3 moisture resistance rating, the binoculars remain reliable during light rain or sleet.

The close focus distance of 16 meters makes them best suited for observing distant objects. For improved image stability during extended viewing, the binoculars can be mounted on a tripod using the built-in tripod adapter, without the need for additional accessories.

Comfort and Practical Functionality

These binoculars combine bright optics, ergonomic design, and rugged construction to provide a comfortable and stable viewing experience. They are well suited for exploring celestial objects, star clusters, and distant natural landscapes.
