Celestron Nature DX 10×56 binoculars are the perfect companion for your next all-day outdoor adventure. With phase-coated BaK-4 prisms and fully multi-coated optics, Nature DX reveals image detail you won’t find with other entry-level binoculars. A great first step into the world of serious, large-aperture sport optics, the views through Celestron’s 56 mm Nature DX models rival those of more expensive binoculars, at a price to fit your budget. Nature DX’s high quality BaK-4 prisms are phase coated to increase contrast and resolution. Phase coated prisms, combined with fully multi-coated lenses, provide maximum light transmission through the entire optical path, for brighter images, even in low light conditions. With large, 56 mm objective lenses, you’ll notice the increased light-gathering abilities of Nature DX 10×56. Enjoy extra time viewing wildlife at dawn and dusk, when it’s too dim to use smaller binoculars. The 10×56 model provides enough magnification for long-range sighting by day and casual astronomical observing around the campfire. Plus, they’re tripod adaptable to ensure stability during extended viewing sessions. Waterproof, fogproof, and nitrogen purged, these binoculars can withstand the elements. A durable rubber armored, polycarbonate housing protects your Nature DX from damage without weighing you down. Twist-up eyecups with multiple stops ensure proper positioning of the eyes, even for eyeglass wearers.
