		In this book you will learn how dedicated amateurs, using either 
		homebuilt or commercial equipment, regularly produce data that is 
		published in professional journals.  You do not need an automatic 
		telescope, or even vast amounts of spare time to become a valuable 
		observer—this book, written and edited by both professional and amateur 
		astronomers shows you how to gather equipment and design a program that 
		is both personally satisfying and scientifically valuable.  |
