Query: THe Best Introduction to Observational Astronomy

The Stars by H.A. Rey is a classic that is unsurpassed in it's accomplishment of it's intention. It is an introduction to observational astronomy. I have never found a better explanation of astronomical terms, celestial, lunar and planetary movement, and above all, the location and appearance of the constellations. If you don't believe me, read Albert Einstein's comment on the back cover! I have purchased and given away at least 10 copies. When someone asks me for a beginning book on astronomy I always recommend this and a pair of binoculars, (or its companion book for younger readers "Find The Constellations"). Most people will recognize the type and illustrations as the work of the author of the Curious George series of children's books.
