Oberwerk 25×100 Deluxe CF Binoculars

Description

Engineered for deep-sky stargazing and long-range terrestrial glassing with the convenience of a central focus mechanism, the Oberwerk 25×100 Deluxe CF Binoculars deliver high-contrast stereoscopic resolving power and massive light gathering. Pairing high-power 25x magnification with colossal 100mm objective apertures, this Porro prism observation system produces a 126-foot linear field of view at 1000 yards (41.8m at 1000m), an actual angle of view of 2.4 degrees, a 4mm exit pupil, and 15mm of eye relief for resolving lunar rilles, deep-sky star clusters, and distant mountain landmarks.

The optical configuration incorporates high-density BaK-4 Porro prisms mounted on precision floating mounting plates that protect collimation alignment against field impacts, paired with fully broadband multi-coated optics across all air-to-glass surfaces. Built inside a braced and hinged all-metal optical body encased in slip-resistant protective rubber armoring, the binocular measures 47cm (18.5 Inches) in length and weighs 4.5 kg (10 lbs). The optical tubes are dry nitrogen gas filled and O-ring sealed for all-weather waterproof and fogproof performance. Mechanical adjustments feature a central focus wheel with a 164-foot (50m) close focus distance, a right-eye diopter adjustment ring, multi-position twist-up eyecups, an interpupillary distance range from 56mm to 74mm, and an integrated heavy-duty structural tripod mount.

Key Features of Oberwerk 25×100 Deluxe CF Binoculars

Designed as one of the largest center-focus observation binoculars available, this 25×100 Porro prism instrument combines massive 100mm light collection with fast focal adjustment. Its floating prism mounting plates protect internal optical alignment from mechanical bumps during transit. The nitrogen-sealed waterproof metal chassis, integrated tripod mount, and custom aluminum hard case ensure rigid stability and all-weather dependability during outdoor observation sessions.

• 25x magnification power combined with massive 100mm objective apertures for deep-sky resolving reach
• Porro prism optical architecture incorporating high-density BaK-4 glass for enhanced depth perception
• Floating prism mounting plates preserving factory collimation against field bumps and vibration
• Broadband multi-coated optical surfaces maximizing photon transmission across dark night skies
• Linear field of view of 126 feet at 1000 yards (41.8m at 1000m) with 2.4-degree actual angle of view
• Comfortable 15mm eye relief with twist-up rubber eyecups accommodating prescription eyeglasses
• Central focus wheel with a right-eye diopter adjustment ring for convenient focal tracking on moving targets
• Nitrogen-purged all-metal waterproof housing featuring an integrated heavy-duty tripod mount

100mm Objective Apertures & Floating BaK-4 Porro Prisms

The 100mm front objective elements collect immense photon volume, generating a 4mm exit pupil that renders faint emission nebulae, galaxies, and open star clusters with remarkable clarity against dark skies. High-density BaK-4 Porro prisms mounted on floating plates provide total internal reflection, preventing optical vignetting and preserving edge sharpness across the visual field. Broadband multi-coatings across all optical faces minimize reflections, allowing observers to distinguish fine structural details across dark sky backgrounds.

Center-Focus Mechanism & Braced All-Metal Chassis

The 18.5-inch all-metal chassis features braced and hinged objective barrels that provide structural rigidity to maintain factory collimation under field transit while keeping total weight to 4.5 kg. Slip-resistant rubber armoring cushions against physical knocks and provides a secure hold during setup. The easy-to-reach central focus wheel allows fast focal adjustments when scanning between celestial horizons and distant moving terrestrial targets, while the integrated tripod mount balances the instrument on heavy-duty video heads or parallelogram mounts.

• Convenient central focus wheel allowing quick focal adjustments across variable target distances
• Submersible nitrogen-purged all-metal chassis resistant to heavy dew and rain condensation
• Integrated structural tripod mount providing balanced, vibration-free attachment to tripod heads
