They exist but most of them have only one speed, that is tracking starts.
SATs are much much faster. So it is important to take that into
account at the time of looking for telescope motors.

There is always the question about movement. You focus on the SAT and
the background will be lines. You focus on the background to get a
stary night and the SAT will be a line.
