High power, low weight and great for astronomy! Other high-power binoculars may have excellent optics, but they can also be, quite literally, a pain in the neck. The Zhumell 20x80 SuperGiants, though, weigh in at just 4.4 pounds, light enough to use comfortably in the field. Still, they are equipped with an integrated tripod mount for use with any standard photographic tripod. That"s just in case you don"t feel like holding onto your binoculars all the time. High-Performance Features * Extra-large field of view with crystal clarity from edge to edge * BaK4 prisms for excellent light transmission * Fully multi-coated optics * Ultra-smooth center focus that"s easy to operate, allowing you to pinpoint your subject * Right diopter adjustment so you can fine-tune your viewing Most impressive, though, is the sheer size of the 20x80 SuperGiants. The 80mm objective lens diameter is huge. In fact, you won"t find many larger, and definitely not in the Zhumell"s price range. Interpupillary distance adjusts from 2.25 inches to 2.75 inches. Once you try these big binoculars for astronomical or terrestrial viewing, you won"t want to go back to anything smaller. And, given all the Zhumell"s advantages, there"s simply no reason you"d have to. For more information on binoculars for astronomy check out our article on Astronomy Binoculars. Built-in Tripod Adapter for ultra-steady viewing These binoculars features a built-in tripod adapter for quick and easy connection to your favorite tripod. It uses a standard 1/4-20 thread that is common on all tripods. The tripod adapter can be adjusted to help balance the weight of the binocular. We recommend using a tripod when viewing single objects like Saturn or Jupiter. The need for a steady image is very important when viewing objects like planets. But for simply panning the nights stars, these binoculars can also be hand-held. Not just for astronomy... These binoculars are not simply for astronomical use. Point these at a far off ship in the ocean or at the buildings off in the distance and you will immediately find yourself 20 times closer! Great for viewing long-distance landscapes and other terrestrial objects. These binoculars find themselves just as comfortable on Earth as they do viewing away from it. Focusing these binoculars is easy. There is a large center-focus wheel that adjusts smoothly and easily. When viewing an object like Jupiter, you will also see Jupiters moons surrounding the enormous planet. A helpful hint is to focus the binocular to get Jupiters moons as tight as possible, and that will bring Jupiter into its best focus. When viewing the craters on the moon it can be helpful to focus the binoculars while looking at the darker areas of the moon for getting that sharp focus.
