A finderscope is a small wide-field telescope mounted on a larger telescope that helps an observer quickly aim at terrestrial or celestial objects. Because of their light gathering capacity, finder scopes are especially useful for finding faint celestial objects that cannot be seen with the unaided eye using non-magnifying finders such as a Telrad or red dot finder. Many telescopes come only with a non-magnifying finder, while others come with a simple low-cost, low-aperture finder scope that gives dim, inverted views that make it difficult to use. Whether you are looking to add a magnifying finder to your telescope or upgrade your present finder scope, this article will guide you through options for selecting the right product for your telescope.
