How To Use An Astronomical Telescope

Astronomy has never been a more popular pastime than it is today. The increased availability of less expensive, more powerful, and more sophisticated telescopes has given rise to a new generation of stargazers. And for these beginning astronomers here is the comprehensive book covering everything from the difficult task of selecting an instrument to the equally daunting choices that arise when a telescope is turned to the heavens.
Renowned British astronomer and author James Muirden takes the fledgling astronomer by the hand in his new book, offering tips on:
* the purchase, assembly, and orientation of your new telescope
* how to observe and chart the Sun, Moon, planets, stars and comets
* how to investigate the deep-sky objects -- clusters, nebulae, and other galaxies beyond the Milky Way
The final chapter, "Windows into Space," explores ten carefully selected regions featuring noteworthy examples of double stars, galaxies, and nebulae, as well as more obscure objects seldom examined by astronomers.
How to Use an Astronomical Telescope offers completely revised and updated location charts with detailed coordinates, tables, appendixes, and numerous illustrations and photographs, making it the essential volume for one's first exploration of the cosmos.

CHAPTER 1

Astronomical Telescopes

What is a telescope? It is an instrument that forms an image of a distant object, and it is thanks to a marvelous property of light rays -- that they can be bent or "refracted" by a piece of glass, or reflected by a shiny surface -- that telescopes are possible. With mirrors, or glass lenses, we can manipulate light rays in any way we wish, casting images of remote objects onto the eye's highly sensitive screen, the retina. Countless nerve endings then transmit the color and intensity responses from different parts of this image to the brain, which in turn decodes the information and... see more
