The Levenhuk Bruno BASE 20x80 is a powerful binocular model designed for users who want to observe details of lunar craters, the moons of Jupiter, and bright nebulae. It is a starting point for serious astronomical observations, even in moderate lighting conditions. The device is also well-suited for observing distant terrestrial objects.
These binoculars provide 20x magnification, which allows for detailed observation of very distant objects. The 80mm objective lenses have a large aperture for low-light observation. The device is based on fully multi-coated optical elements: Porro prisms made of BaK-4 glass and K9/ZF1 lenses. As a result, the optical elements feature high light transmission and provide a detailed image without edge distortion. The 4mm exit pupil allows for observations before dawn or at dusk. The +4D diopter adjustment helps to focus the image in case of a difference between the right and left eye, and the smooth central focus allows for quick adjustment on an object.
The body of the device is made of an aluminum alloy. It is covered with a rubber coating that provides a secure grip and shock protection. Thanks to the IPX3 moisture resistance, there is no need to stop observations during a drizzle or sleet, without worrying about the binoculars' operation. Due to the 16m close-focus distance, this model is better suited for observing distant objects rather than nearby ones, and the use of a tripod (sold separately) takes the weight off the user's hands and stabilizes the image. Mounting on a tripod does not require additional adapters; a built-in adapter can be used.
The binoculars combine bright optics, thoughtful ergonomics, and a durable construction, ensuring maximum comfort during observations. This allows the user to focus on exploring the secrets of the Solar System, bright star clusters and nebulae, as well as the most inaccessible places on Earth.
