Because today''s amateur astronomical telescopes are both powerful and affordable, spectroscopy - once the province of professionals - is becoming more and more popular. Various spectroscopes, at prices to suit everyone, are now available "off the shelf". Practical Amateur Spectroscopy contains everything an amateur needs to grasp the basic principles, to begin observing, and to understand just what the spectra show. Contributions by leading practical amateurs from America and Europe cover a very wide range of amateur equipment and techniques. One even describes how an audio CD can be used to show solar emission and absorption lines!

An increasing number of people are taking advantage of the relatively low prices of astronomical equipment. Many of these people are doing so with little knowledge of practical astronomy and, as the volume of questions asked at astronomical society meetings and on internet newsgroups attest, there is a need for these questions to be answered in one place. Hence this book. The fundamental premise behind AstroFAQs is that the beginning amateur astronomer wishes to get "up and running" with the minimum delay. A secondary premise is that anyone will better appreciate why something is done as it is if there is an understanding of the underlying principles. AstroFAQs addresses both these premises. AstroFAQs makes no pretence to go into great depth -that would be impossible in such a slim volume -but it will give you the kick-start you need to choose and use your instrument effectively, and will take you to a level of expertise that is significantly higher than the "beginner" status. It uses a hierarchical section num­ bering system that simplifies cross-referencing. Suggestions for more in-depth reading are given throughout. More and more "newbie" astronomers are entering this fascinating hobby by purchasing one of the "gee­ whiz" GOTO telescopes, of which there is an increasing selection. These serve the wish to begin observation as soon as possible, but they do so at a price premium.

This book contains everything an astronomer needs to know about binocular observing. The book takes an in-depth look at the instruments themselves. It has sections on evaluating and buying binoculars and binocular telescopes, their care, mounting, and accessories. In addition there is a selection of fifty fine objects to be seen with 50mm and 100mm binoculars. The advantages of using both eyes for astronomical observing are many and considerable, largely because of the way the human brain processes visual information. This book enables the astronomer to maximize those advantages.
