    Big eyes for the skies!

    Celestron's SkyMaster 25x100, large-aperture astronomy binoculars offer phenomenal performance for astronomical viewing. They are also a great choice for terrestrial use, especially over long distances.


    Although marketed as the "SkyMaster" name, these astronomy binoculars are very often purchased for long-distance terrestrial viewing. They're perfect for use on a balcony or patio from a home with a view. Point any SkyMaster Binocular up to the stars and your eyes will pop with amazing star fields. Jupiter and its moons, the rings of Saturn, and globular star clusters are all very visible from any of the SkyMaster Series Binoculars. If you are fortunate enough to live in a dark-sky environment, such objects as galaxies and nebulae are also within reach of a Celestron SkyMaster Binocular.

    All models feature high quality BaK-4 prisms and have multi-coatings for enhanced contrast. The SkyMaster Series Binoculars are available in SkyMaster 12x60, SkyMaster 15x70, SkyMaster 20x80 and the SkyMaster 25x100.

    All of the Celestron SkyMaster binoculars are water-resistant and each is tripod adaptable. The SkyMaster 20x80 and SkyMaster 25x100 are waterproof and have an integrated tripold adapter rod for simple connection to any standard photographic tripod.
