Altitude azimuths are widely used in astronomy to locate celestial objects in the sky. These coordinates represent the altitude, or angle above the horizon, and azimuth, or angle east or west of due north, of an object in the sky. While altitude azimuths are the most commonly used coordinate system in astronomy, there are other methods for locating celestial bodies, including equatorial coordinates and galactic coordinates. Equatorial coordinates use the celestial equator and the position of the Earth to locate objects in the sky, while galactic coordinates use the plane of the Milky Way galaxy. However, altitude azimuths remain the go-to coordinate system for most stargazers due to their simplicity and convenience.
