There are several ways to achieve this. For example, from the menu bar: Chart → Chart Coordinate System → Alt-Az Coordinate

Solar System Probably you want to simulate movement of planets, asteroids or comets in whatever coordinate system. You need to set them visible, also here there are several ways.
