Abstract
An improved technique balances a telescope from the viewpoint of the motors that drive the telescope's axes. A motor that controls movement along an axis of the telescope drives the telescope in one direction and then in the opposite direction. Motor current is measured while the motor is driving the telescope in each direction, and a difference in motor current is computed. The difference in motor current indicates the degree of imbalance of the telescope, which may be communicated to an operator to allow adjustments to the telescope to improve its balance.
