APPENDIX D: TRAINING THE DRIVE
Train the telescope motors using Autostar II. Perform this procedure if you are experiencing any pointing accuracy problems. Fig. 41 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 exer- cise once every 3 to 6 months to maintain the highest level of telescope pointing accuracy.
1Verify that AUTOSTAR INITIALIZATION is complete.
