Celestron SkyMaster 15x70 binoculars are porro prism binoculars designed for either terrestrial or celestial viewing. The 70-mm objective lens is multi-coated for better light transmission while the BaK-4 glass prisms provide increased contrast and resolution. The 15x magnification brings objects in for greater detail without being so large they cannot be held, though the SkyMaster 15x70 binocular has a built-in tripod adaptor for longer viewing sessions. Celestron SkyMaster binoculars come with a carrying case, and are backed by a Limited Lifetime warranty.

They could be worse.
I read frequent online comments about collimation problems inherent, esp. in the 15x70s. Don't know really what to think: am I one of the lucky few or are these reviewers not setting the IPD nearly well? Mine had no such noticeable defect, looking at the moon, looking at telephone wires. I backed off from the eyepiece about 6" and even so the images touched at the same point, as closely as I could perceive. If there is a complaint it would need to be two-fold: multi-coated (not 'fully...') and only water resistant in lieu of the far preferable waterproof.
But, for astronomy. At a truly dark site (Bortle 1), that I truly wish is within your reach, I could, with the Skymaster 15x70s, see with averted vision nebulosity around and in the Pleiades! And M42 revealed direct tendrils of ionized gas - without color, of course, as humans are incapable of detecting those wavelengths, if what I hear is true.
Anyway, why not save a boatload of change and go with good ole Celestron, even if they now make them in China. Wasn't the founder of the outfit first to bring a truly great 'scope to the general public? I recall Johnny Carson bragging about his. My '70s 11x80s were by my side at every sorte into the Arizona desert, when the Owl Nebula was visible in the city limits!
