Celestron SkyMaster 15x70 Binoculars

Make Long-Range Observations or Explore the Night Sky First is the extra-wide 70mm objective aperture, which allows lots of light and delivers good visibility in low-light conditions. Second is its high 15x magnification power, which enables you to have good close-ups on distant objects, even the moon and the stars. This binocular configuration allows you to observe celestial objects with both eyes, an advantage over regular telescopes. Also, it is fully assembled and ready to be mounted on a tripod using the included adapter. To ensure that you get clear images, without glare, the lenses are anti-reflection multi-coated. Other highlights of the optic are its centre focusing, interpupillary adjustment, and diopter corrector. To protect this instrument while not in use, also included are objective lens covers, a rainguard for the eyepieces, and a carry case.

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.
