The book starts with a brilliant introduction to observing deep sky objects. It continues with a section describing equipment used for deep sky observation. In the introduction, you'll learn about (or be refreshed on) topics like multiple stars, stellar magnitudes, declination and right ascension, clusters, nebulae, galaxies, etc.

In the section on observation equipment, you'll find details on binoculars and telescopes, advantages and disadvantages of different sizes, types, and features of both types of instruments. Loads of information on the various accessories you'll need for your observing sessions are found in this section. Also, several planetarium software packages and star atlases are described in detail.

The constellation maps are very thorough and photos of the region (mostly at 60' field width) show what the DSOs look like on film. The star maps typically show a 10 to 15 degree field width, with a 5 degree finder field and a 1 degree eyepiece field. The maps use black stars on a white background.

The Thompson duo have provided a great guide to observing that brings me back to astronomy after many years away from the hobby. I think this book will hook you in as well.
