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

The polycarbonate and aluminum housing allows the binocular to be lighter weight without sacrificing its durability. The housing with protective rubber armor 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.

Customer Reviews

Superb choice for an astronomy binoculars! Review by Fox
Overall Score
I previously bought a pair of Saxon 20x80 binoculars and wasn't completely satisfied with the quality. The team at Optics Central were friendly and quick to organise a substitute pair of Celestron SkyMaster Pro 20x80 for me.

They are superb fun for anyone looking to buy a great pair of powerful binoculars. The visuals are clear and crisp, the binoculars a breeze to handle and not too heavy (but tripod recommended). The kit also comes with great accessories such as a handy carry bag and eye pieces. One thing that didn't really appeal to me was that changing the eye pieces from one to the next can be a little tedious, but isn't something major that dims the experience.

In short, the SkyMaster Pros won't disappoint, and would be an awesome gift for somebody! (Posted on 21/02/2018)
