SkyMaster Pro binoculars are the ideal choice for amateur astronomers or anyone that observes at great distances.

Description

Compared to lower-priced large aperture binoculars, SkyMaster Pro uses superior optics, coatings, internal parts and housing materials. With large objective lenses, BaK-4 prisms and fully multi-coated optics utilizing Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro is second to none at this price point.

Massive Objective Lenses

The 80mm 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 RSR “Reflex Sight Ready” Rail

The built in tripod adapter of the SkyMaster Pro 20x80mm 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

The polycarbonate and aluminum housing allows the binocular to be lighter weight without sacrificing its durability. The housing with protective rubber armour is extremely rugged and durable with the ability to handle 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.

Enhanced Magnification

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.
