Star chart

A celestial map by the Dutch cartographer Frederik de Wit, 1670

A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. They are used to identify and locate constellations, stars, nebulae, galaxies, and planets.[1] They have been used for human navigation since time immemorial.[2] Note that a star chart differs from an astronomical catalog, which is a listing or tabulation of astronomical objects for a particular purpose. Tools using a star chart include the astrolabe and planisphere.
