Astronomy for everyone

This guide is very well done. The first part, besides the preface of Mr. Reeves, always interesting, remember the basics. The second part describes the constellations with the alignments to identify them. The last part gives information to "go further". I recommend the purchase of "Celestial Map Mobile" Mr. Pierre Bourge, a simple way to view the portion of the celestial sphere at the latitude of Paris (thus valid for France) according to the date and time of observation.
