After aligning an equatorial mount, the Right Ascension (RA) axis is parallel to the Earth's rotation axis. To track celestial objects over a day, it is therefore enough to make a complete turn around this axis in 24 hours, turning in the opposite direction of the Earth's rotation.

This is the main advantage of the equatorial mount compared to the altazimuth mount. To do this, a knob or fine adjustment cable is typically used, but it is possible to fully automate the rotation using a motor with sidereal drive speed.
