Yes, just tilt the rotator pipe to point to the North Star and you got
it.  This is the low budget way to follow AO-40 with one motor just like
any Satellite TV dish since AO-40's track across the sky is always within
about 10 deg of the geostationary satellite arc and only changes very
slowly... see
