Earth rotates at 1670 kilometers/hour, the Moon travels at 3,683 kilometers per hour, tidally locked to Earth so the telescope travels at that speed. However, the Moon has a lot further to travel so a more meaningful measure is change in angle over time. For the purpose of a "long exposure" the Moon would have a lot less smear.
Earth: 7.2921159 × 10−5 radians/second (sidereal, not including solar orbit, at equator)
Moon: 0.2.66169 × 10−5 radians/second (on average for its eliptical orbit)
