Features

The Celestron SkyMaster 20x80 is built with features that prioritize light gathering, durability, and ease of use for high-power observation:

• Giant 80mm Objective Lenses: The large aperture provides exceptional light-gathering ability, delivering maximum image brightness for superior performance in low-light conditions and for observing faint astronomical objects like nebulae and star clusters .

• High-Quality BaK-4 Prisms: Constructed with BaK-4 glass prisms, these binoculars ensure sharp, high-contrast images with excellent resolution and minimal light loss .

• Multi-Coated Optics: All air-to-glass surfaces feature multi-coatings to increase light transmission, reduce glare, and enhance contrast for clearer, brighter views .

• Powerful 20x Magnification: This high magnification brings distant celestial and terrestrial subjects incredibly close, allowing for detailed observation .

• Integrated Tripod Adapter: A built-in tripod adapter rod allows for ultra-stable mounting on any standard photographic tripod. This is essential for the 20x80 model, as its weight and power make handheld use impractical for steady viewing .

• Porro Prism Design: The widely spaced Porro prisms provide a enhanced three-dimensional perspective and are often preferred for their classic design and depth perception .

• Ergonomic and Protective Rubber Armor: The durable rubber covering provides a firm, non-slip grip and protects the binoculars from minor impacts during use .

• Long Eye Relief: With 17-18mm of eye relief, it is designed to be comfortable for eyeglass wearers, allowing them to see the full field of view .

• Large Center Focus Knob: A large, centrally located focus knob enables smooth and easy focusing, even when wearing gloves .
