The sky observer's guide

A guide for observing the night sky with an emphasis on using optical aides such as telescopes and binoculars. Also touches on naked-eye observing with sections on sky colors such as rainbows, auroras, the zodiacal light and meteors. Understanding astronomical time is also detailed. This is not a guide to identifying the constellations. The authors assume the reader will already have that knowledge. The highlight of the book are the numerous and excellent paintings, illustrations and diagrams by John Polgreen.
