Black 9x50 Achromatic Finder Scope
Large-aperture finder scopes let you see fainter objects than smaller finders, and this one will literally show you the light! It has a fully coated, 50mm achromatic objective lens with adjustable focus. It has 9x magnification and a standard (inverted) 5.5-deg field of view with superimposed crosshairs. The aluminum tube is baffled and blackened inside to enhance contrast. This finder comes with a cast-aluminum bracket with a dovetail foot that fits most Orion telescopes. A dovetail mounting base is also available for installation of this finder scope on non-Orion telescopes. Alignment of the finder scope is easy and intuitive by virtue of two perpendicular nylon thumbscrews and an opposing spring-loaded pin. Weighs 16 oz. Black.
