Telescope-Porro Prism Binoculars-Celestron 20 x 80 SkyMaster Pro Waterproof Binoculars

What We Love About Celestron SkyMaster Pro 20 X 80 Binoculars

• Extra-large 80 mm optics are perfect for astronomy, nature observations, and long-distance viewing of all kinds.

• Celestron’s highly regarded XLT coatings have been applied on all air-to-glass optical surfaces of the SkyMaster Pro 20×80 Binoculars. This attention to quality, together with the inclusion of BAK-4 prisms, results in high contrast, tack sharp images that you will love.

• Like all giant binoculars, the Celestron 20 X 80 SkyMaster Pros perform best when mounted on a tripod. These binoculars come with a built-in tripod adapter, making it easy to enjoy hands-free observations.

• Do you ever have a hard time finding your subject when viewing through binoculars? The Celestron 20×80 SkyMaster Pro includes a innovative RSR “Reflex Site Ready” finder rail, which allows you to incorporate a red dot finder into your binocular observing sessions! Using a red dot finder on these binoculars is similar to using one on a telescope. Once you align the finder with the binoculars, you will be able to pinpoint your subject in a flash.

• Waterproof & fogproof! The Celestron SkyMaster Pro 20 x 80 Binoculars have been nitrogen-purged to prevent fogging during temperature fluctuations or damp conditions, and the housing is waterproof so that you don’t have to worry about getting caught in the rain, or having dew seep into the optical housing.

• Another small yet thoughtful addition to the SkyMaster Pro line is the addition of two sets of eye guards, aka eye cups. One set is round, and can be used most of the time, but when you have light entering from the side (which decreases contrast considerably) you can switch to the included winged eyecups.
