The Celestron SkyMaster Pro binoculars are the ideal choice for amateur astronomers or anyone that observes at great distances. SkyMaster Pro uses superior optics, 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 price point.

The 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.

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.

The built in tripod adapter of the SkyMaster Pro 20x80 allows the binocular to be attached to a tripod for added stability during longer viewing sessions and also allows a red-dot finder to be attached to it utilizing the included RSR "Reflex Sight Ready" Rail. When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly.

The tripod adapter included with the SkyMaster Pro not only allows the binocular to be attached to a tripod for added stability during longer viewing sessions, but also includes a removable rail for attaching a red dot finderscope. When properly aligned with the binocular, a red-dot finder helps you locate objects quickly and center them in the binocular.

A polycarbonate and aluminum housing makes SkyMaster Pro durable and lightweight. The housing’s protective rubber armor is extremely rugged and can stand up to tough use.

The fully waterproof housing for use in all weather conditions provides peace of mind when unexpected weather rolls in. 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.

15.5 mm of eye relief allows for comfortable viewing for both eyeglass and non-eyeglass 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.

Bring distant objects into view with 20x magnification—great for observing celestial objects in greater detail, searching for wildlife in the brush or viewing a distant object on the horizon
