Philip's Deep Sky Observer's Guide is a practical introduction to deep sky observing, explaining in straightforward, non-technical language what is meant by the 'deep sky', and how to observe the Universe beyond our Solar System. Many people have been inspired by the incredible images returned from the Hubble Space Telescope and wish to see such objects for themselves. While the views through Earth-based telescopes may not be as spectacular as those obtained from space, it is a huge thrill to look at such famous objects as the Triangulum Galaxy or the Horsehead Nebula. Deep sky observing has become a very popular activity for skywatchers. Philip's Deep Sky Observer's Guide is suitable for observers with small- to medium-sized telescopes, or even binoculars. It begins by introducing the basics of observing and explaining what equipment is required. Each type of deep sky object is then dealt with chapter by chapter - galaxies, globular clusters, diffuse nebulae, open clusters, double stars, planetary nebulae and supernova remnants. Each chapter recommends a number of objects or 'targets' to view, and the author describes how to find them and what to expect to see, as well as providing important data and tips for drawing or photographing the target. A complete set of star maps marks all the objects included in the book, and additional charts are provided for targets that are tricky to locate.
