Description
Celestron’s SkyMaster Series of large aperture binoculars are a phenomenal value for high performance binoculars ideal for astronomical viewing or for terrestrial (land) use – especially over long distances. Each SkyMaster model features high quality BaK-4 prisms and multi-coated optics for enhanced contrast. Celestron has designed and engineered the larger SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions.
Celestron Skymaster 15X70MM Porro Binoculars
The 15×70 version is one of the most popular models in the series. It offers large and therefore light-gathering aperture in a handy and reasonably lightweight configuration. Via the supplied adapter it can be attached to a photo tripod. With its good-natured insight properties, it can also be held by hand for a short time (hint: Hold it a s close to the lenses as possible and let it rest under the eyes), but its full potential can only be used together with a tripod. Especially in the sky, the larger aperture and magnification offer details which remain hidden in smaller instruments.
