Excerpt from In Starland With a Three-Inch Telescope: A Conveniently Arranged Guide for the Use of the Amateur Astronomer, With Forty Diagrams of the Constellations and Eight of the Moon HE sole purpose of this book is to afford a convenient guide for the amateur astronomer when engaged in telescopic observation. Aside from a study of the moon's surface, the observa tion of double stars is sure to prove the most attractive work for the possessor of a small telescope. The brighter doubles the novice will have no difficulty in finding, but those below the third magnitude are often difficult to locate without reference to a diagram of the constella tion of which it is a part - hence the author has seen fit to place such a diagram where it can be easily consulted. It is presupposed that the owner of the telescope is familiar with the constellations. It then should be an easy matter, with the assistance of the accompanying diagrams, to find the double stars mentioned in the text. The constellations are grouped under the seasons for the sake of convenience. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
