slew

(rotating a telescope to point it)

To slew a telescope is to move (rotate) it in order to aim it. In the case of a space telescope, it may mean rotating the entire craft. The word is used as a verb and also as a noun, meaning an instance of such movement. A slew angle is the angular distance covered by a slew, and a slew time is the length of time taken to carry it out. A slew speed (in angle per second) may be cited for an observation or sequence of observations, or may be cited as a capability of a telescope.
