Combining a high magnification and oversized objectives, the Celestron 10x50 Ultima Porro Binoculars is an ideal optic for making detailed observations at long distances, even in challenging lighting conditions.

The large lenses draw in copious amounts of light and, combined with the 10x power, translate to a comfortable exit pupil that will completely cover most fully dilated pupils in low-light conditions, such as those at dawn or dusk and when peering into heavy brush or canopies. Complementing these performance features are anti-reflection fully multicoated optics, a wide field of view, long eye relief, and a traditional Porro prism optical path that all work together to produce an immersive and comfortable observational experience, featuring bright, clear high-contrast views with accurate color rendition and a rich depth of field. The wide field of view helps to mitigate the appearance of distracting hand shake that is common with higher power optics, for clearer views.

For long-duration glassing sessions, to reduce arm fatigue, or to eliminate vibrations, the Ultima binocular can be tripod mounted using an optional adapter. Its optical tubes are nitrogen filled and O-ring sealed to a waterproof IPX6 rating and resistant to internal fogging and the chassis is made of a lightweight and durable aluminum alloy and wrapped in a protective slip-resistant armor. Fold-down rubber eyecups mold themselves to your eye sockets to block stray peripheral light for brighter views without intrusive side glare, and the binoculars' center-focusing wheel is also slip resistant to make precision focusing fast and easy.
