Train the telescope motors using Autostar. Perform this procedure if you are experiencing any pointing accuracy problems. Fig.
52
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.

APPENDIX C: TRAINING THE DRIVE
Further Study....
This manual gives only the briefest introduction to astronomy. If
you are interested in pursuing further studies in astronomy, a
few topics are suggested below that are worth reading up on
(some of the topics are easy and some are quite challenging).
Try looking up some of these in the Autostar glossary.
Also included below is a small sampling of books, magazines
and organizations that you might find helpful.
Topics
1. How is a star born? How does a solar system form?
2. How is the distance to a star measured? What is a light
year? What is red shift and blue shift?
3. How are the craters on our Moon formed? Is there water
under the surface of the Moon?
4.
What is a black hole? A neutron star? A quark star? A
gamma burster? An Einstein lens?
5. What are stars made of? Why are stars different colors?
How is the elemental composition of a star determined?
What is an Lyman Alpha forest?
6. What is the difference between a Type 1 and a Type II
supernova?
7. What is the importance of studying the composition of
comets? Where do comets come from?
8. How old is our Sun? Will our Sun evolve into a planetary
nebula or go supernova?
9. What is the Inflationary Big Bang? What is dark matter?
What are MACHO's?
10. How are extrasolar planets discovered? What is an accre-
tion (or protoplanetary) disk?
11. What are the differences between elliptical, spiral and irreg-
ular galaxies? Can globular clusters be older than the uni-
verse itself?
