An Introduction To Telescopes
The naked eye is unable to see objects that are too tiny or too far. But telescopes allow the naked eye to get a good view of distant objects. You must have heard of, seen or used a telescope.
Telescopes are devices that are endowed with magnifiers to allow you to see things magnified with a clear view. Telescopes are commonly used in science or its branches, particularly astronomy and physics.
How does a telescope work? Two lenses are installed in a telescope. This makes viewing a distant object possible. Each of the lenses has a function. The objective lens, or the primary mirror, collects the illumination radiated by the object viewed and makes it readily available in a certain focus point. The eyepiece lens picks up the vivid light from the focus point and spreads it to the retina so that viewing becomes possible.
There are various determinants to good object viewing in the telescope. An efficient telescope ought to possess the competent quality of collecting light from the object that is viewed and the capacity to magnify the image.
The diameter of the lens or the mirror employed in the telescope determines the collection of light. It is also termed aperture. Logically, the better the aperture, the more light it is able to gather. Image enlargement, however, is entirely dependent upon the blending of lenses. It is the eyepiece of the telescope that does the magnification.
The prices of telescopes vary with the specifications and capacities. You can also purchase accessories that will conjure with your telescope?s image. Whether you station a telescope on your veranda for a delightful stargazing experience, or you opt for a toy telescope, the function of the telescope remains the same -- to enable you to take a clear view of far away objects.

New Cosmic Horizons: Space Astronomy from the V2 to the Hubble Space Telescope
New Cosmic Horizons: Space Astronomy from the V2 to the Hubble Space Telescope
New Cosmic Horizons tells the extraordinary story of space-based astronomy since the Second World War. Starting with the launch of the V2 rocket in 1946, this book explores the triumphs of space experiments and spacecraft designs and the amazing astronomical results that they have produced. David Leverington examines the fascinating way in which the changing political imperatives of the United States, USSR/Russia and Western Europe have modified their space astronomy programs. He covers all major astronomy missions of the first fifty years of space research: the Soviet Sputnik and American Explorer projects, the subsequent race to the moon, solar and planetary missions, and the wonders of modern astrophysics culminating in the exciting results of the Hubble Space Telescope. Extensively illustrated, New Cosmic Horizons offers amateur and professional astronomers an unusual perspective on the history of astronomy in our time. David Leverington was Design Manager of the GEOS Spacecraft and Meteosat Program Manager for ESA in the 1970s. During his tenure as Engineering Director at British Aerospace in the 1980s, he was responsible for the Giotto spacecraft that intercepted Halley's comet, and the Photon Detector Assembly and solar arrays for the Hubble Space Telescope. He is a Fellow of the Royal Astronomical Society. He lives in Essex, England.
