Not all binoculars are created equal, especially when they are expected to perform well in low light conditions. Observations during twilight and at night require larger optics to collect as much light as possible, but big lenses alone are not enough to ensure a superior viewing experience. It also takes quality glass and rugged construction to keep your binoculars safe and working well for years to come. Celestron's large-aperture Echelon series binoculars were designed for use in low light conditions. Whether you are long-range glassing across a field or valley, or gazing at the night sky, a pair of Celestron Echelon binoculars will get the job done. With an exit pupil of 7 mm, these binoculars deliver the maximum amount of light your pupils can accept, allowing you to see the most detail possible. The Echelon 10x70 offers the lowest magnification of any Echelon model, giving it the widest field of view. Choose this model if you are new to high-power, large-aperture binoculars, as they will make it easiest to acquire and follow your subject. The 10x model is also a great choice for viewing large swaths of the night sky, comets, the Milky Way, and more.
