Modern astronomical telescopes, along with other advances in technology, have brought the deep sky - star clusters, nebulae and the galaxies - within reach of amateur astronomers. Given a site with clear, dark night skies everything else follows. This book provides the reader with everything he needs to know about what to observe, and using some of today's state-of-the-art technique and commercial equipment, how to get superb views of faint and distant astronomical objects. But, rather than the plethora of books emphasizing imaging for later viewing, this book explores what can be done in real time at the location and during the viewing session.
