The Celestron 15×70 SkyMaster Binoculars are specifically designed for long-range observations and stargazing, offering two key features that set them apart from other binoculars. Firstly, the extra-wide 70mm objective aperture allows for excellent light gathering, providing clear visibility even in low-light conditions. Secondly, the high 15x magnification power enables you to get close-up views of distant objects, including the moon and stars.These binoculars offer the advantage of observing celestial objects with both eyes, a benefit over traditional telescopes. They are fully assembled and ready to be mounted on a tripod using the included adapter, ensuring stable viewing. To minimize glare and enhance image clarity, the lenses are equipped with anti-reflection multi-coatings. Other notable features include center focusing, interpupillary adjustment, and a diopter corrector.FeaturesOptical SpecificationsMagnification: 15x, providing a detailed view of distant objects.Objective Lens Diameter: 70mm (2.75 inches), maximizing light intake for excellent low-light performance.Angular Field of View: 4.4°, offering a broad view of celestial objects.Linear Field of View: 231 ft @ 1000 yds (77 m @ 1000 m), suitable for observing expansive scenes.Exit Pupil: 4.7mm (.18 inches), ensuring sufficient light transmission.Eye Relief: 18mm (.71 inches), ideal for eyeglass wearers.Close Focus: 43 ft (13 m), allowing for observation of nearby objects.Interpupillary Distance: Adjustable from 56mm to 72mm (2.20 to 2.83 inches), accommodating various users.Prism Type: High-quality BaK-4 Porro Prisms for superior optical quality.Lens Coatings: Multi-coated for enhanced light transmission and clarity.Design and BuildPorro Prism Design: Offers excellent light transmission and image quality.Protective Rubber Covering: Provides a secure grip and protects against minor impacts.Large Center Focus Knob: Easy to use for precise focusing.Tripod Adaptable: Includes a tripod adapter for stable viewing.Carrying Case: Included for safe storage and transport.Additional FeaturesWater Resistant: Protects against moisture, though not fully waterproof.Weight: Approximately 48 oz (1361 g), requiring a tripod for extended use.
