The C 10x50 ACP Binocular from BSA Optics is a fully coated, Porro prism binocular with BAK7 glass designed for all types of outdoor activities. The popular 10x magnification and 50 mm objective increases the light gathering capability of the binocular which translates into greater detail and sharper image clarity, attributes which are especially useful in low light conditions or distance viewing. This terrestrial designed binocular can deliver wide angle breath-taking views of the Moon's terminator or the Pleiades in addition to an Earth bound purple-mountain-majesty panorama. The fully coated magnesium fluoride (MGFL-2) blue BAK7 porro prisms deliver crisp, clear images with increased light transmission. A threaded mount receptacle has been designed into the housing to allow an adaptor to be attached to the binocular for use with a tripod or window mount. A large tactile center focus knob makes for fast and precise focusing. An eyepiece diopter adjustment allows customization for each individual eye affording less eyestrain over long-term viewing. They have a black rubber ribbed finish for a comfortable, secure and slip-free grip. This is an all around scope suitable for a multitude of applications.
