Celestron 15x70 SkyMaster Pro ED Binoculars
Far simpler to use than a telescope, the Celestron 15x70 SkyMaster Pro ED Binoculars are made for astronomy and offer an easy way to explore the night sky. They excel at long-range terrestrial glassing as well. Extra-low dispersion lenses, multiple coats of antireflective XLT coating, and wide objective lenses combine to produce bright, high-contrast views with accurate color fidelity. Binoculars this powerful require a stable support, so the SkyMaster Pro ED can be mounted on a tripod with an optional adapter. Special eyepiece threads allow the use of 1.25" astronomical filters to improve your viewing experience.
