This guide is organized by month and provides lunar phases, planet activity, constellation maps and tables of planet and star movement, and sky activity and events. Each month has all the compass points, dates, and exact times to view the planets. There are also monthly constellation maps with dates, times, and hourly rates of comets, fireballs, and meteor showers. Skywatchers in the United States and Canada won’t miss a thing, even with just binoculars. Amateur astronomers have come to rely upon and expect each year’s edition of this proven sell-through title. It is the handy reference they grab as they head out to do some skywatching, and now they can use it to plan an astrovacation.
