APPENDIX D: TRAINING THE DRIVE

Train the telescope motors using AutoStar. Perform this procedure after RESET or if you are experiencing any point- ing accuracy problems. Figure 33 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.
