Star hopping is a technique that is often used by amateur astronomers to locate objects in the night sky.
Star hopping uses bright stars as a guide to finding fainter objects. A knowledge of the relative positions of bright stars and target objects is essential. After planning the star hop with the aid of a star chart, the observer first locates one or more bright stars in a finderscope, reflex sight, or, at a low magnification, with the instrument to be used for observation. The instrument is then moved by one or more increments, possibly using a reticle to identify specific angular distances, to follow identified patterns of stars in the sky, until the target object is reached.
