赤道仪
赤道仪是以一根平行于地球自转轴旋转的轴，就能追随着天空（天球）旋转的仪器设备。这种类型的设备常用于望远镜、卫星碟和相机。赤道仪的优势在于它能够允许联接在其上的设备只需要以固定的速率驱动一根轴就可以追踪天空中以周日运动运行的任何天体。当做为卫星碟时，赤道仪的设备允许只转动一根轴就能同时指向好几颗地球同步卫星。

Equatorial mount 赤道仪
An equatorial mount is a mount for instruments that compensate the rotation of earth by having one rotational axis parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any object in the sky that has a diurnal motion by driving one axis at a constant speed. Such an arrangement is called a sidereal drive.
