The Celestron SkyMaster 25x100 are massive, high-performance Porro prism binoculars built primarily for long-range terrestrial and astronomical viewing.
• Magnification & Aperture: 25x magnification with giant 100mm objective lenses that gather maximum light in low-light and night conditions.
• Optics: Multi-coated optics paired with high-quality BaK-4 glass prisms for increased contrast, resolution, and vivid clarity.
• Focusing System: Individual eyepiece focus instead of a central focus wheel, allowing precise, independent adjustments for each eye.
• Field of View: 3-degree angle of view (approx. 156 feet at 100 yards / 52 meters at 100m).
• Eye Relief: 15mm of eye relief, making them usable—though tight—for eyeglasses wearers when rubber eyecups are folded down.
• Physical Build: Weighs roughly 8.75 to 9 lbs (nearly 4 kg) and features enhanced structural body reinforcement with a protective rubber armoring.
• Mounting: Includes an integrated, rigid photo [tripod adapter rod](index:0.6.1, 0.6.12) because their heavy weight and high magnification require a sturdy tripod for a stable, vibration-free image
Bogen Professional Tripod (3011) included.
