The telescopes were referred to as 'The Equatorial Group' because originally all the telescopes were mounted on equatorial mounts. An equatorial mount compensates for Earth's rotation by having one rotational axis parallel to the Earth's axis of rotation. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed.
