The two most popular designs among amateur astronomers are the German equatorial mount and the fork mount.
Alternatively, many telescopes come on equatorial mounts. These mounts compensate for Earth’s rotation by keeping on the rotational axis parallel to Earth’s axis of rotation. Because of this, the mount can stay fixed on a celestial object just by moving one axis at a constant speed. The two most popular designs among amateur astronomers are the German equatorial mount and the fork mount. Both are widely available with computerized aiming and tracking systems. Many amateurs prefer equatorial mounts, but bear in mind that some mounts — especially the German equatorial style — can be much heavier than alt-azimuth mounts.
