Unlike other sciences, astronomy welcomes contributions from ama- teurs. Much of the knowledge we have on subjects such as comets, meteor showers, variable stars, the Moon, and our solar system comes from observations made by amateur astronomers. So as you look through your Meade DS-114AT telescope, keep in mind Galileo. To him, a tele- scope was not merely a machine made of glass and metal, but some- thing far more— a window through which the beating heart of the uni- verse might be observed.

Galileo's discoveries laid the founda- tion for understanding the motion and nature of the planets, stars, and galaxies. Building on his foundation, Henrietta Leavitt determined how to measure the distance to stars, Edwin Hubble gave us a glimpse into the possible origin of the universe, Albert Einstein unraveled the crucial relationship of time and light, and 21st-century astronomers are cur- rently discovering planets around stars outside our solar system. Almost daily, using sophisticated successors to Galileo's telescope, such as the Hubble Space Telescope and the Chandra X-Ray Telescope, more and more myster- ies of the universe are being probed and understood. We are living in the golden age of astronomy.

Also below is a small sampling of books, magazines, and organizations that you might find helpful.

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.

In the early 17th century Italian Scientist Galileo, using a telescope smaller than your DS-114AT model, turned it skyward instead of looking at the distant trees and mountains. What he saw, and what he realized about what he saw, has forever changed the way mankind thinks about the universe. Imagine what it must

have been like being the first human to see moons revolve around the

planet Jupiter or to see the changing phases of Venus! Because of his

observations, Galileo correctly real- ized Earth's movement and position around the Sun, and in doing so, gave birth to modern astronomy. Yet Galileo's telescope was so crude, he could not clearly make out the rings of Saturn.
