Levenhuk Bruno PLUS 20x80 Binoculars
Levenhuk Bruno PLUS 20x80 astronomy binoculars are made for demanding users. If you have been dreaming about an alternative to a large telescope for a long time and are looking for a compact version with similar capabilities, these binoculars will not disappoint you! They are perfect for studying the night sky and will become your faithful assistant in the exploration of the Moon, planetary disks and meteor showers.
The optics in the binoculars consist of Porro prisms and fully multi-coated lenses made of BaK-4 glass. Five-element eyepieces transmit a flat image across the field of view and reduce any distortions of the picture to a minimum. The powerful zoom allows you to view remote objects in detail, and the high-aperture lenses are not affected even by dark winter nights. Binoculars are perfect for observations at any level of illumination.
The binoculars’ shell is made of aluminum and prevents water penetration. Ins ide, it is filled with nitrogen, so the lenses will not fog up during rapid temperature changes. The shell has a tripod mounting jack so you can mount the binoculars on a tripod. In addition, you will be able to adjust the sharpness, change diopters on the right eyepiece, set up the interpupillary distance, and reposition the twist-up eyecups if needed.
