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
