The Celestron Ultima 10x50 binocular has a wide 6° field of view, or 315 feet wide when measured at a distance of 1,000 yards. It is the perfect choice for watching wildlife, nature, or sports when you need a high magnification binocular with large, generous 50 mm objectives to gather lots of light. But the possibilities don’t stop there. Ultima binoculars are great for almost any activity, including sporting events, sightseeing, birding / wildlife observation, hiking, and more! Take it all in, wherever you are. This binocular is comfortable to use and provides great images, even in situations when the light level is lower, like dusk or very overcast conditions.
These classically styled binoculars use their Porro prism optical design to provide optimal image clarity and depth of field. Their widely spaced objective lenses enable enhanced triangulation between binocular and subject, presenting the observer with a rich, three-dimensional image that only traditional Porro prism binoculars can offer.
Ultima binoculars feature fully multi-coated optics. A binocular is only accurately described as “fully multi-coated” when all of its air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye. The prisms inside Ultima binoculars are made of high quality BaK-4 glass so that more light is reflected off their internal faces and passes through to the eye. With this technology in their design and manufacture, the fully multi-coated lenses and BaK-4 prisms of the Celestron Ultima 10x50 binocular maximize light transmission for remarkably bright, highly detailed images. Their large 50 mm aperture objectives are good for their extra light gathering capability, which you will appreciate when the light level gets dim.
A durable, synthetic rubber-armored, aluminum housing protects your Ultima binoculars from damage without weighing you down. Viewing through Ultima binoculars is comfortable for both eyeglass wearers and non-eyeglass wearers, thanks to the synthetic fold-down rubber eyecups. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. Ultima binoculars will be able to stand up to even the toughest environmental factors and outdoor conditions.
The Ultima 10x50 binocular features a close focus of just 22.9 feet, making it perfect for wildlife observers, general naturalists, sports, marine observing, and many other activities. For distance viewing, the 10x50 model offers a wide field of view so you can easily follow moving subjects. Keep your Ultima binocular at the ready with the comfortable included neck strap. This Ultima 10x50 binocular from Celestron is also tripod-adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (photography through the eyepiece). The Celestron tripod adapter for this purpose is optional and is sold separately. The binocular also includes an adjustable neck strap and a protective padded case for storage and transport.
