The Sky-Watcher 8x56 Binocular from Celestron is a sleek, superb quality binocular that rivals the very best models. They're typically judged as having exceptional performance for the price. The 8x56 model is great for big game or long distance birding in any light, and is also appropriate for astronomy use. They are nitrogen-purged waterproof and fogproof. Full size porro prism units will always have a place thanks to their great depth of field and three-dimensional views, and now you won't have to choose them with trepidation thanks to their waterproofing.
These Sky-Watchers have BAK4 prisms and are fully multicoated with twist-up eyecups for quick adjustment and optimum eye relief. They come with a protective rubber covering that offers a firm, slip less grip. The large center focus knob is a great convenience. A carrying case is included.
