For planetary imaging no as rotation of field isn't a problem with such short exposures. Nor for visual use is one needed.

For longer exposure deep sky photography you need to tilt it to your latitude and align to the pole to prevent rotation of the field. A wedge is a good way of doing this, though not the only one it is the easiest for most. Though I don't know of the drive is up to long exposures, I've never used one this way.
