Levenhuk Bruno PLUS 30x80 Binoculars (85538)

Levenhuk Bruno PLUS 30x80 Binoculars (85538)

The Levenhuk Bruno PLUS 30x80 binoculars are designed for observers who want to explore the most distant celestial and terrestrial objects. They reveal detailed lunar surface structures, the phases of Venus, and close binary stars. Even with high magnification, the 2.4° field of view remains wide enough to easily locate and track targets.

High Magnification and Strong Light-Gathering Power

With 30× magnification, these binoculars provide excellent detail for long-distance terrestrial and astronomical observation. The large 80 mm objective lenses collect significant light, making them effective in low-light conditions.

The optical system is built around BaK-4 Porro prisms and K9/ZF1 glass lenses with full multi-layer anti-reflective coatings. This ensures bright, high-contrast images across the entire field of view. The optics deliver clear and rich detail, even when observing dim objects, which is especially valued in astronomy.

Durable, Weatherproof Construction

The aluminum alloy body is fully sealed to the IP67 standard, providing protection against dust and temporary immersion in water. Nitrogen filling prevents internal fogging during rapid temperature changes, such as those experienced during nighttime observation. A rubberized exterior enhances grip and protects against impacts.

Three-position twist-up eyecups allow comfortable viewing with or without glasses. Central focusing and ±4 diopter adjustment enable quick and precise focus tailored to individual eyesight differences.

Tripod Mounting Recommended

Due to the high magnification and weight, handheld observation may lead to image instability and fatigue. For optimal stability and comfort, tripod mounting is recommended. The binoculars feature a built-in adapter compatible with any standard 1/4" tripod, eliminating the need for additional accessories.
