Celestron Ultima 8x32mm Porro Binoculars - see everything clearly. 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. COATINGS & PRISMS Ultima binoculars feature fully multi-coated optics to ensure the maximum amount of light passes through the glass to the eye. The prisms are made of high quality BaK-4 glass so that more light is reflected off their internal faces and passes through to the viewer. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images. THE BODY 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. These binoculars are also fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. EXCELLENT VERATILITY The Ultima 8x32mm binoculars feature a close focus of just 8.2 feet, making it perfect for birders and wildlife observers, museum visiting, and any other activities involving close-up viewing. For distance viewing, the 8x32mm model offers an ultra-wide field of view so you can easily follow subjects such as birds or insects in flight, athletes on the sporting field or performers on a stage as they move. WAYS TO OBSERVE Keep your Ultima binocular at the ready with the included neck strap. It’s also tripod-adaptable (tripod adapter is sold separately).
