The stars are getting closer with the Levenhuk Bruno PLUS 15x70 binoculars for astronomical observations! It's perfect for exploring the night sky. These binoculars will allow you to observe the Moon and planets, watch meteor showers, and explore large, bright constellations and star clusters. The capabilities of the Levenhuk Bruno PLUS 15x70 astronomical binoculars are comparable to a basic refractor – it will be a perfect replacement for a bulky telescope.
These binoculars feature classic Porro prisms, which bring together a lot of light and make the image as clear and contrasted as possible. Powerful, large-aperture objective lenses that not only offer excellent magnification, but are ideal for observing the starry sky at night. The diameter of the exit pupil is 4.7 mm. All optical elements are made of BaK-4 glass and the lenses are treated with numerous layers of anti-reflection coating. The five-element eyepieces minimize optical and geometric distortions and transmit an ideally flat figure across the field of view.
The body of these binoculars is made of aluminum. It is durable, reliable and protected from drops and vibrations. The airtight design protects the optical elements from rain, dust and dirt. Inside, the binoculars are filled with nitrogen, which prevents the lenses from fogging up in case of sudden temperature changes. For convenient observation, the Levenhuk Bruno PLUS 15x70 astronomical binoculars can be mounted on a standard tripod.
The rich functionality allows you to adapt the binoculars to your needs. Adjusting the sharpness and correcting the diopter of the right eyepiece is done easily and conveniently. You can choose the most convenient position for the inverted eyelets. Three fixed positions are available.
