Celestron's SkyMaster Pro binoculars are ideal for amateur astronomers, nature and sports enthusiasts or for anyone that observes at great distances. Compared to lower-priced large aperture binoculars, the SkyMaster Pro series use superior optics, optical coatings, internal parts and housing materials. With large objective lenses, BaK-4 prisms and fully multi-coated optics utilising Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro is second to none at this impressive price point.
The SkyMaster Pro binoculars feature:
Massive Objective Lenses: Large 80 mm objective lenses have tremendous light gathering capabilities, delivering superior low light performance, even in the dimmest conditions. Choose SkyMaster Pro for use at dusk, dawn and nighttime astronomical viewing.
Fully Multi-Coated Optics and BaK-4 Prisms: Every air-to-glass optical surface is multi-coated with Celestron’s proprietary XLT coating technology. These coatings, coupled with BaK-4 prisms, increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution.
Built in Tripod Adapter and RSR “Reflex Sight Ready” Rail: The built in tripod adaptor of the SkyMaster Pro 20x80 not only allows the binocular to be attached to a tripod for added stability but it also acts as a balance rail by sliding along the center support rod. A red-dot finder can also be attached to the center support rod utilizing the removable rail. When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly.
Lightweight, Waterproof Construction: A combination of polycarbonate and aluminium makes the SkyMaster Pro housing durable and lightweight. The housing’s protective rubber armour is extremely rugged and can stand up to tough use.
The binoculars have a fully waterproof housing for use in all weather conditions and provides peace of mind. The housing is also filled with dry nitrogen gas to prevent the internal lenses from fogging when moving between extreme temperatures or when using the binocular in damp conditions.
Enhanced Magnification: Get closer to the action by bringing distant objects into view with the binoculars' 20x magnification. The magnification is great for observing celestial objects in greater detail, searching for wildlife or viewing a distant object on the horizon.
