Training the Drive
Train the telescope motors using Autostar. Perform this procedure if you are experiencing any pointing accuracy prob-
lems. Fig. 32 depicts the complete Drive Training procedure.
NOTE: Use a terrestrial object, such as a telephone pole or lamp post, to train the drive. Complete this
exercise once every 3 to 6 months to maintain the highest level of telescope pointing accuracy.
