The UpClose G2 10x50 Porro Binoculars from Celestron offer a large magnification for exceptional up-close detail with the even larger light transmission abilities of 50-millimeter objectives. These binoculars are a top performer in low light conditions such as dawn dusk or an overcast day. Good on the hunt or for outdoor panoramic vistas they are an excellent choice to double as an astronomical sky scanner. The exceptionally wide 68-degree Apparent Angle of View (AAoV) is greatly appreciated here. The Pleiades and the Moon's terminator never looked so awesome. The 10x50 binoculars are at the far end of comfortably handheld viewing without experiencing the effects of the wobbles. A tripod thread has been integrated into the chassis for stable viewing over long durations.The UpClose G2 10x50 Porro possesses multi-coated optics for brighter sharper higher contrasted viewing. The classic Porro prism design lays out better three-dimensional imaging with less light loss. The outdoor factor has not been ignored. Water resistant with a rubber-covered aluminum housing they are endowed with finger ridges and thumb indents. Fold the rubber eyecups down for eyeglasses or sunglasses and extend them with glasses for the maximum field of view. These are all-around binoculars offering a large size factor but just within the limits of a handheld steady view.
