Making Your Own Telescope - Hardcover By Thompson, Allyn J. - GOOD

"Between the covers of this book are complete and detailed instructions for making your first telescope. Step-by-step directions, and numerous diagrams by the author, enable you to produce an instrument which will reveal markings on the surface of the moon little more than a mile across; the divisions in the rings of the planet Saturn; stars of the 13th magnitude, only1/500 as bright as the faintest star visible to the naked eye."
