PDF Ebook The Telescope (Classic Reprint), by Louis Bell
Excerpt from The TelescopeThis book is written for the many observers, who use telescopes for study or pleasure and desire more information about their construction and properties. Not being a handbook in two or more thick quartos, it attempts neither exhaustive technicalities nor popular descriptions of great observatories and their work. It deals primarily with principles and their application to such instruments as are likely to come into the possession, or within reach, of students and others for whom the Heavens have a compelling call.Much has been written of telescopes, first and last, but it is for the most part scattered through papers in three or four languages, and quite inaccessible to the ordinary reader. For his benefit the references are, so far as is practicable, to English sources, and dimensions are given, regretfully, in English units. Certain branches of the subject are not here discussed for lack of space or because there is recent literature at hand to which reference can be made. Such topics are telescopes notable chiefly for their dimensions, and photographic apparatus on which special treatises are available.Celestial photography is a branch of astronomy which stands on its own feet, and although many telescopes are successfully used for photography through the help of color screens, the photographic telescope proper and its use belongs to a field somewhat apart, requiring a technique quite its own.It is many years, however, since any book has dealt with the telescope itself, apart from the often repeated accounts of the marvels it discloses. The present volume contains neither pictures of nebulae nor speculations as to the habitibility of the planets; it merely attempts to bring the facts regarding the astronomer's chief instrument of research somewhere within grasp and up to the present time.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

An historically important book, but maybe not for you, and probably not in this edition By Ursiform Note: I actually posted this for the 2010 Nabu Press reprint, which is the link above following "This review is from:". Amazon has cross-posted the review to the Dover edition, which is the link in the text below. Same original book, different reprints by different publishers, and different ISBNs. Sorry for any confusion.This is a reprint of Louis Bell's classic 1922 treatise on the telescope. It is quite technical. While it does cover some of the history of the telescope, it is primarily about how telescopes and the instruments used with them are designed and built. Page 65, for example, is a table labeled "Characteristics of Optical Glasses". Randomly opening the book to page 175 we find the sentence: "It will be seen that the friction studs are carried by the fly balls themselves, somewhat as in Fraunhofers' construction a century since, and the regulation is very easily and quickly made by adjusting the height of the conical friction surfaces above the balls." If your eyes glaze over at that, this is not a book for you.Simply put, this is neither a popular history of the telescope nor an up-to-date book on designing and building telescopes. Nonetheless, it is an important historical work, and some people will want a copy in their library. (I, obviously, have a copy.) But before buying this edition you should know that there was a 1981 Dover reprint. Although no longer in print, used copies can be found at a reasonable price: The Telescope.The classic history of the telescope is King's book The History of the Telescope, also republished by Dover. While out of print as I write this, Dover is about to release a new printing. Current only through 1955, King provides a detailed and moderately technical history. For a recent, lighter, and easier to read history, I recommend Dunn's The Telescope: A Short History.

It is a constant distraction, which means that reading is slow. Attention to the type detracts from content, some lines completely unreadable (e.g. last line on page 106), and the figures are patchy. It's beyond me why the book was reproduced in an odd size, and even why it was reproduced at all. Amazon should not sell this item.

Best technical book on classic telescopes By RAB I'm delighted to have gotten a hardbound copy of what is perhaps the best English-language book on telescopes, their design and testing, and use, up to around 1910. Fairly technical, but worth the effort to read, and you'll learn things that remain important with today's instruments.
