Bruno PLUS 25x70 Binoculars
Features:
Levenhuk Bruno PLUS 25x70 Binoculars are created for those who are interested in the distant corners of space and fascinating terrestrial landscapes. The device allows you to examine the relief of lunar craters, dimly luminous nebulae, star clusters at night, and during the day – the smallest elements of a distant landscape or the behavior of wild animals from a safe distance.
The binoculars provide a 25x magnification for the detailed observation of distant objects. The 70mm objective lenses guarantee high aperture and image brightness across the entire field of view. The optical system is based on classic Porro prisms of BaK-4 glass with a high refractive index and large objective lenses of K9/F4. All of the optical elements have a multi-layer anti-reflective coating that increases light transmission. The binoculars provide a resolution threshold up to 4 arcseconds and that allows you to see the target in the slightest detail. Central focusing wheel with smooth motion makes it possible to bring the image into focus nice and easy.
The aluminum alloy body is complemented by a rubber coating and is completely sealed according to the IP67 standard. The device is protected from dust, heavy rain, and short-term immersion to a depth of one meter. Nitrogen filling prevents the optics from internal fogging during rapid temperature changes. Diopter adjustment +4D and twist-up eyecups with three fixable positions ensure precise adjustment for individual eyesight peculiarities. The device maintains a secure grip even when wearing gloves, and the mechanical strength of the structure can withstand accidental impacts in the field. All of this makes the binoculars a durable companion for the most demanding amateur astronomers and naturalists who value the combination of optical power and readiness for unpredictable weather.
It is recommended to mount the binoculars on a tripod to obtain a completely stable image and reduce the strain on your hands. Tripod mounting is performed using an adapter from the kit. It is compatible with any tripod of 1/4" standard. The adapter is made of metal.
