Backed by the Royal Astronomical Society of Canada, this easy-to-tote softcover reference is a must for serious sky watchers. Mortillaro takes a more in-depth, technical approach to some topics (navigating the sky with a telescope), but chapters on the moon and planets will be accessible to novices observing from their backyards. For each month, the author lists events such as meteor showers, the phases of the moon, detailed star charts, and other information. Intermediate astronomers and beginners eager to learn more will find this volume highly useful as they watch the skies throughout the year.
