Levenhuk Bruno PLUS 20x80 astronomy binoculars are powerful binoculars with high-aperture objective lenses through which you will be able to observe the Moon in detail, explore planets of the Solar system and watch meteor showers. This optical device will easily substitute for a bulky refractor. These binoculars’ capabilities easily invite the comparison to entry-level telescopes. Levenhuk Bruno PLUS 20x80 astronomy binoculars are an excellent choice for the city and countryside observation.

The optical scheme of these binoculars consists of classic Porro prisms and fully multi-coated lenses. Each element is made of special BaK-4 glass, enabling these binoculars to transmit crisp and contrast images without distortions. The five-element eyepieces are also worth noting. They even the field of view and minimize chromatic aberration of the image.

The optics of these binoculars are covered with a durable aluminum shell for better protection. It is hermetic and is not afraid of bad weather. Besides, the nitrogen filling prevents the lenses from fogging. You may continue observation even in severe weather conditions.

When you use binoculars of high magnification, you may obtain the best image while observing from a tripod. Therefore, Levenhuk Bruno PLUS 20x80 astronomy binoculars have a standard diameter connector. You will be able to move from hand-held observations to static study of space and landscapes at any time. For convenient observations through binoculars, you can adjust the interpupillary distance, adjust the diopter on the right eyepiece, or set the position of the twist-up eyecups.

I was thinking of buying a telescope, but decided to opt for these binoculars instead. I have a camera tripod, so now it is very convenient to look at terrestrial objects, as well as stars. Moreover, I can even see Jupiter and a few of its moons as dots.
