From the reviews: "The author, who is a well-known Portugese amateur astronomer, methodically explains how to recognize the brighter stars and major constellations and, thus, how to find one's way around the night sky. ... This book does an effective job of doing what it sets out to do. I recommend it to anyone who wants to explore the night sky for the first time and understand how the night sky visible to us changes during the night and during the year."

This book comprises a nice selection of careful thought out diagrams which fit in beautifully with the text ... . I would really recommend it to someone who is new to astronomy or as a reference book for the regular observer. ...
