Sporting a moderate magnification and larger objectives, the Celestron 8x42 Ultima Porro Binoculars are a general-purpose optic for mid- to long-range use, even in challenging lighting conditions.

The large lenses draw in a generous amount of light and, combined with 8x power, translate to a wide exit pupil that will completely cover most 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 coated optics, a wide field of view, and a traditional Porro prism optical path that all work together to produce an immersive and comfortable observational experience that is defined by bright, clear high-contrast views with accurate color rendition and a rich depth of field.

For long-duration glassing sessions, to reduce arm fatigue, or to eliminate vibrations, the Ultima can be tripod mounted using an optional adapter. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging, and it chassis is made of a lightweight and durable aluminum alloy and wrapped in a protective slip-resistant synthetic rubber 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.
