Product Details


  • 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. SkyMaster models feature 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.

    Never look directly at the Sun with the naked eye or with this optic. Permanent and irreversible eye damage may result. Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
