This instruction book shows how to make home-made telescopes. It has six different sizes and styles, from a small hand-held device to a large mounted telescope. All are made with readily-available, inexpensive materials, and will provide information on stars, comets, eclipses and constellations, and other phenomena. The authors claim that these telescopes are far better than the instruments used in Galileo's or Newton's time. The guide is free of cumbersome technical jargon, and should be accessible to anyone interested in understanding the skies. The book also traces the development of the telescope, and teaches the principles and variations of design, basic construction techniques and materials. It shows how to repair and adapt older telescopes and how to take photographs through a telescope.
