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: The 70 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 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 Reflex Sight Rail (RSR): The built in tripod adaptor allows the binocular to be easily attached to a tripod for added stability during longer viewing sessions The adaptor also allows a red-dot finder to be attached to it utilising the included RSR (“Reflex Sight Ready”) Rail. When properly aligned with the binocular, the red-dot finder will allow objects to be found and 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 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.

Extended Eye Relief: The binoculars have 17 mm of eye relief that allows comfortable viewing for both spectacle and non-spectacle wearers. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses on. For those that do not wear eyeglasses, the rubber eyecup positions the users eye behind the eyepiece at the correct distance for optimal viewing.

Enhanced Magnification Bring distant objects into view with 15x magnification—great for observing celestial objects in greater detail, searching for wildlife in the brush or viewing a distant object on the horizon.
