Overview
Celestron SkyMaster 20x80 Binoculars – Multi-Coated Optics
Explore the night sky and distant landscapes with the Celestron SkyMaster 20x80 Binoculars. Combining powerful 20x magnification, large 80mm objective lenses and BaK-4 Porro prisms, these binoculars deliver bright, detailed views for astronomy and long-range terrestrial observation. Multi-coated optics improve light transmission and contrast, while an integrated tripod mounting rod provides stability during extended viewing sessions. Designed for stargazers, outdoor enthusiasts and long-distance observation, the SkyMaster 20x80 offers impressive optical capability in a durable, rubber-armoured body.
Key Features
- 20x Magnification: Brings distant subjects closer, making these binoculars suitable for observing the Moon, star clusters, distant landscapes and wildlife from established viewing locations.
- 80mm Objective Lenses: Large apertures gather more available light than smaller binocular lenses, supporting brighter views in low-light conditions and astronomical observation.
- Multi-Coated Optics: Anti-reflective lens coatings improve light transmission and help reduce unwanted reflections, delivering clearer images with enhanced contrast.
- BaK-4 Porro Prisms: High-quality prism glass supports detailed, well-defined images, while the Porro prism configuration provides a natural sense of depth when observing distant subjects.
- Wide Field of View: A 3.7-degree angular field provides a viewing width of 65 metres at 1,000 metres, helping users locate and follow distant subjects.
- 18mm Eye Relief: Generous eye relief improves viewing comfort, particularly for spectacle wearers, while adjustable interpupillary distance accommodates different users.
- Integrated Tripod Mount: The built-in mounting rod supports attachment to a compatible tripod, helping minimise image shake during high-magnification viewing and extended observation sessions.
- Durable Rubber-Armoured Construction: Protective rubber covering provides a secure grip, while the large central focus wheel enables convenient adjustments. The body is water-resistant, not waterproof.
- Included Accessories: Supplied with a nylon carrying case, objective lens caps, rainguard, neck strap, lens cloth and instruction manual for convenient storage, transport and maintenance.
