Description

Stars are getting closer with Levenhuk Bruno PLUS 15x70 Binoculars for astronomical observations! They are great for exploring the night sky. These binoculars will allow you to observe the Moon and planets, watch meteoric showers, and explore large and bright constellations and star clusters. The capabilities of Levenhuk Bruno PLUS 15x70 astronomy binoculars are comparable with an entry-level refractor – they will be an excellent replacement for a bulky telescope.

These binoculars are based on classic Porro prisms, which collect a lot of light, and make the image as clear and contrast as possible. Powerful and high-aperture objective lenses not only have excellent magnification, but are also great for night observation of the starry sky. The exit pupil diameter is 4.7mm. All optical elements are made of BaK-4 glass, and the lenses have several layers of anti-reflection coating. Five-element eyepieces minimize geometric and optical distortions and transmit an ideally flat picture throughout the field of view.

The shell of these binoculars is made of aluminum. It is durable, reliable and protected from falls and vibrations. The hermetic design protects the optics from rain, dust and dirt. Inside, the binoculars are filled with nitrogen, which prevents the lenses from fogging during rapid temperature changes. For convenient observation, Levenhuk Bruno PLUS 15x70 astronomy binoculars can be mounted on a standard tripod.

Rich functionality allows you to adapt the binoculars to your needs. Adjustment of sharpness and diopter correction of the right eyepiece is done easily and smoothly. You can choose the most convenient position for the twist-up eyecups. There are three fixed positions available.

Eyecups: three fixed positions

Questions and Answers
Colin Moss (2020.12.16)
I've just received these amazing binoculars. The clarity is truly astonishing and the field of view is perfect. Yes they are a tad heavy but just find a comfy seat that you can lean back on and rest your elbows and you'll be so glad you've bought them. I was viewing Orion nebula on Monday night 14th December and was fortunate to see a Geminid meteor flash past right before my eyes, perfectly clearly. Read the best astro binocular reviews on the web, they're not wrong. I belong to an astronomy club and the members are well impressed with them. I cannot recommend them enough.

Would you please confirm the closest focus for these binoculars.
Is it 14 metres or 14 feet?
Many thanks
