    • Description

      Step up your stargazing experience with SkyMaster Pro, the much-anticipated upgrade to the world's bestselling astronomy binocular, the Celestron SkyMaster. Designed with amateur astronomers in mind, this new model boasts lots of handy new features that will make your stargazing experience that much more comfortable.

      The 20x80 is a perfect size when you want to see impressive detail in your favorite celestial objects and maximum resolution in long distance terrestrial viewing. Although 20x80s can be cumbersome and should be mounted on a tripod, SkyMaster Pro's new polycarbonate housing makes it more manageable than others in this size range.

      Superior optical performance

      Long distance binoculars can easily run into the hundreds of dollars (and beyond!), but SkyMaster Pro gives you all the most important upgrades while keeping the price affordable and accessible. Of course, you get a fully waterproof, nitrogen purged and rubber armored housing that you can use confidently in the field. 

      What's more, all optical surfaces are fully multi-coated with Celestron's acclaimed XLT optical coatings. These coatings--also used on their monster observatory telescopes--dramatically boost light transmission so you can see maximum detail in objects. SkyMaster also features BaK-4 prisms for even brighter, high contrast images.

      Finally, Celestron has added two sets of folding rubber eyecups: traditional round and winged eyecups to shield your eyes from stray light.

      Designed for the amateur astronomer

      Celestron has solved one of the most frustrating problems with binocular astronomy--locating those faint fuzzy targets. They've done this by adding a "RSR" or "Reflex Sight Ready" rail to the top of the binocular. You can attach any standard red dot finderscope like Celestron's StarPointer or StarPointer Pro in one step, so locking in on your target is quick and painless. The RSR rail is part of the SkyMaster Pro's innovative built-in tripod adapter, so you won't have to tote along a separate accessory to attach it to a tripod, either.

      Add the SkyMaster Pro 20x80 binoculars to your arsenal of astronomy gear and enjoy a new perspective on your favorite hobby.
