Íàçâàíèå: How To Make A TelescopeÀâòîð: Texereau J. Àííîòàöèÿ: ". . . Borrowed from my high school library more than 20 years ago, the earlier book (the First Edition) was my introduction to an avocation that has occupied many evenings and weekends since. That fondly remembered volume forms the core of this new one, with many additions to complement and expand the older text. Reading the text in preparation for this review was like rediscovering an old friend. Key to the book's quality is Texereau's writing style, his workshop hints, diagrams and where appropriate, expansions into theory. The accent is upon the practical — details of just what it takes to fabricate an optical telescope . . ." "In the sections devoted to optics both novice and experienced "glass-pushers" will receive guidance that is as clear and in-depth as any that can be found in print . . ." "From the earlier edition he has retained complete instructions on the fabrication of a Newtonian telescope, including optics and mounting, and provides a well-written rationale for its choice as the novice's first telescope. For the new edition he has added detailed plans for the construction of a Cassegrain telescope, including both the primary and secondary optics. He even devotes a section—definitely not novice stuff — to fabrication of an optical window . . ." "I heartily recommend this new edition of How to Make a Telescope, both to the recently interested telescope maker and the seasoned "telescope nut." Novices will find the spicy, well-illustrated and detailed book that inspired me many years ago, while even old hands should find some new wrinkles within its greatly enlarged text...
