APPENDIX D

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.

DS-2000 TIPS

This manual gives only the briefest introduction to astron- omy. If you are interested in pursuing further studies, a few topics are suggested below that are worth reading up on. Try looking up some of these topics in the Autostar glossary.

Also 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? How old is the Moon and Earth? How old is the Sun?

4.What is a black hole? A neutron star?

5.What are stars made of? Why are stars different col- ors? What is a white dwarf? A red giant? Have we ever seen the surface of a star besides our own Sun?

6.What is a nova? A supernova?

7.What are comets? Minor planets? Meteors? Meteor showers? Where do they come from?

8.What is a planetary nebula? A globular cluster?

9.What is the Big Bang? Is the universe expanding or contracting, or does it always remain the same? What is dark matter?

10.What is an extrasolar planet? What is an accretion (or protoplanetary) disk?

11.What is the difference between an elliptical, a spiral, and an irregular galaxy?
