The Levenhuk Bruno PLUS 20x80 astronomical binocular is a powerful binocular with large-aperture objective lenses, allowing you to observe the Moon in detail, explore the planets of the solar system, and watch meteor showers. The optical instrument can easily replace a large refractor. The capabilities of this binocular easily invite comparisons with basic telescopes. The Levenhuk Bruno PLUS 20x80 astronomical binocular is an excellent choice for observations in the city and countryside.
The optical scheme of this binocular consists of classic Porro prisms and fully multi-coated lenses. Each element is made of special BaK-4 glass, which enables this binocular to transmit clear and high-contrast images without distortion. The five-lens eyepieces are also noteworthy. They uniform the field of view and minimize chromatic aberration of the image.
The optical elements of this binocular are housed in a durable aluminum body for better protection. It is hermetically sealed and weather-resistant. The nitrogen filling also prevents lens fogging. You can continue observations even in poor weather conditions.
When using binoculars with high magnification, you can achieve the best image while observing from a tripod. For this reason, the Levenhuk Bruno PLUS 20x80 astronomical binocular has a standard diameter connector. You will be able to switch from handheld observations to static study of space and landscapes at any time. For comfortable binocular use, you can adjust the interpupillary distance, adjust the diopter of the right eyepiece, or set the position of the twist-up eyecups.
