The main purpose of binoculars Vixen Giant 16-40x80 BCF
A series of astronomical binoculars
Pancratic binoculars Vixen Giant 16-40x80 BCF has increased (expansion) depending on the distance from the observation object or the need to study fine details without changing the location of the observer. Vixen Giant 16-40x80 BCF is intended to panoramic view and study objects in space (constellations, nebulae, the milky way) can be used for terrestrial observations. Thanks to the special design and high quality optical elements, the instrument provides a clear and vivid picture, as in good daylight and in poor visibility conditions (fog, cloudiness).
Design features of binocular Vixen Giant 16-40x80 BCF
Binoculars Vixen Giant 16-40x80 BCF binocular with variable magnification in the range from 16 to 40 times. With the help of the ground mechanism is a transition from one magnification to another (the lever is set opposite the appropriate value on the graduated scale, located on the inner side of the right eyepiece), and, accordingly, vary such parameters as the exit pupil diameter, angle of view and aperture. Precise tuning of the Vixen Giant 16-40x80 BCF is carried out through the mechanism of Central focusing with a diopter adjustment. After each change of magnification necessary to carry out adjustment of focusing of the image.
Combination system Porro prisms made of optical glass BaK4 fully and multi-layered anti-reflective coating lenses lenses and eyepieces to astronomical binoculars Vixen Giant 16-40x80 BCF provides the best light output by minimizing light loss when passing through optical components, allowing to obtain bright and sharp images. Durable and lightweight waterproof, aluminum alloy reduces the weight of the structure and provides protection from mechanical damage, precipitation and moisture. Rubber coating prevents slipping from the hands during work with binoculars Vixen Giant 16-40x80 BCF. The nitrogen filling prevents fogging from the inside (when the change in temperature or in high humidity conditions).
For mounting on a tripod (the mount) zoom binoculars Vixen Giant 16-40x80 BCF is equipped with a special adapter (tripod mount ¼ in) allows you to balance the binoculars on a tripod.
Operating temperature range from -25°C to + 50°C.
