Celestron 10x50 Ultima Porro Binoculars

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
