Actuator

(telescope control motor)

A telescope's Actuator is a control motor used to physically position the telescope or parts of it. A motor to keep the telescope pointed at an object can go by that name. In large astronomical telescopes, smaller actuators may be used to align Segmented Mirrors to act as a single mirror or to position parts of an Adaptive Optics (AO) system. In a space telescope, the actuators may be positioning the attitude of the entire spacecraft.
