Celestron Skymaster Pro 20x80

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 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 night time 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.

Compatible with Astronomical Filters

Filter threads on the eyepieces allow you to attach standard 1.25” filters to SkyMaster Pro.  These filters can minimize the effects of light pollution, reduce the brightness of the moon or diminish glare when looking over water.  The binocular also includes both standard and winged rubber eyecups.  When lighting conditions are not ideal and there is a lot of glare or light entering from the side, switch to the winged eyecups to block this light and improve the view.

Built in Tripod

The built in tripod adapter of the SkyMaster Pro 20x80 not only allows the binocular to be attached to a tripod for added stability during longer viewing sessions but also allows a red-dot finder to be attached to it utilizing the removable rail.  When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly.

RSR “Reflex Sight Ready” Rail

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.

Lightweight, Waterproof Construction

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.

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.
