David Levy's Guide Variable Stars

Found throughout the universe, variable stars are fascinating objects to observe. Their brightness changes over time and they can easily be seen with even the most basic equipment. David Levy explains how to begin electronic (or CCD) observing, as well as how to observe variable stars through a small telescope or binoculars. Featuring a section on Southern hemisphere stars, this book covers various types of objects that can be observed by amateur astronomers, including more exotic phenomena like gamma ray bursts, blazars, and polars. It will motivate anyone with even a basic interest in astronomy to begin observing variable stars.
