Omegon Binoculars Brightsky 30x100 - 90° + Case (85789)

Omegon Binoculars Brightsky 30x100 – 90° + Case (85789)

The Omegon Brightsky 30x100 binoculars are powerful large-format optics designed for observing both nature and the night sky. Whether you are watching wildlife at dusk, ships in the distance or celestial objects such as star clusters and planets, these binoculars deliver bright, detailed views across long ranges.

With large 100 mm objective lenses, they gather significant light, providing clear and sharp images even in low-light conditions. This version features 90° angled eyepieces, making it especially suitable for comfortable astronomical observations, particularly when viewing objects high overhead.

A robust hard-shell case is included for safe storage and transport. It features a custom-fit interior insert, secure fasteners and a sturdy carrying handle.

Key Features

• 90° angled eyepieces for relaxed observation up to the zenith

• Interchangeable 1.25" eyepieces for flexible magnification options

• Waterproof and nitrogen-filled for reliable performance in damp or wet conditions

• Lightweight magnesium housing for strength and portability

• Fully multi-coated optics for high contrast and reduced reflections

Precision Focusing System

The binoculars use a single focusing system with individual helicoid adjustments for each side. This ensures smooth, accurate focusing and crisp images. Diopter adjustment is available on both sides for precise visual alignment.

Wide-Angle 18 mm Flat-Field Eyepieces

Included 18 mm wide-angle eyepieces provide a 65° apparent field of view. Their flat-field design maintains sharpness across the entire image and reduces distortion at the edges, allowing you to use the full field of view effectively.

Interchangeable Eyepieces and Filter Compatibility

The 1.25-inch eyepiece holders allow you to replace the supplied eyepieces with other astronomical models to adjust magnification as needed. Zoom eyepieces can also be used for continuously variable magnification.

Integrated filter threads enable the use of standard 1.25-inch filters. Light pollution filters can improve nebula contrast, while neutral density filters are useful for observing the Moon.

Two-Eye Viewing Advantage

Each eye has its own optical path, creating a natural and immersive observing experience. Viewing with both eyes enhances depth perception and reduces fatigue during extended sessions.

Magnesium Housing for Reduced Weight

Despite the large 100 mm objectives, the magnesium construction keeps the binoculars relatively lightweight while maintaining high durability. This makes them suitable for field use and transport.

90° Viewing Angle for Astronomy

The 90° eyepiece design allows comfortable observation of objects near the zenith. Compared to 45° models, this configuration provides a more relaxed posture when observing high-altitude celestial targets, helping you detect finer details over longer observing sessions.

Stable Handling and Mounting

A sturdy carrying handle ensures secure grip during transport and setup. The integrated tripod connector on the underside allows quick attachment to a stable tripod. For best results, a solid tripod with a video head or fork mount is recommended.
