Dobsonian Telescopes

A superb guidebook described in Bookwatch as 'the home astronomer's "bible"', Turn Left at Orion provides all the information beginning amateur astronomers need to observe the Moon, the planets and a whole host of celestial objects. Large format diagrams show these objects exactly as they appear in a small telescope and for each object there is information on the current state of our astronomical knowledge. Revised and updated, this new edition contains a chapter with ten new spreads describing spectacular deep sky objects visible from the southern hemisphere, and tips on observing the upcoming transits of Venus. It also discusses Dobsonian telescopes, with hints on using personal computers and the Internet as aids for planning an observing session. Also new to this edition are redrawn "Guidepost" figures at the beginning of each season chapter that allow readers to visualize a three-dimensional view of the sky's dome; redesigned seasonal object layouts that provide more space for the naked-eye charts; a new spread on double stars near Boö tes has been added to Spring, replacing the "Shrinking Double" spread; and a unique "When and Where to Look" table has been added to the last page, among other new features. Unlike many guides to the night sky, this book is specifically written for observers using small telescopes. Clear and easy to use, this fascinating book will appeal to skywatchers of all ages and backgrounds. No previous knowledge of astronomy is needed.

Dobsonian - In astronomy the Dobsonian is a type of alt-azimuth telescope mounting that became popular among amateur astronomers in the 1980s because of its extreme simplicity, low price, and rugged construction. The terms "Dobsonian" or "Dob" may also refer to any telescope that features this type of mount, although the telescopes themselves are typically of Newtonian design.

Isaac Newton Group of Telescopes - The Isaac Newton Group of Telescopes or ING operates the WHT, INT and JKT optical telescopes for PPARC, the NWO and the IAC. The telescopes are located at Roque de los Muchachos Observatory on La Palma in the Canary Islands.

Telescopes In Education Foundation - The Telescopes In Education (TIE) project brings the opportunity to use remotely controlled telescopes and charge-coupled device (CCD) cameras in a real-time, hands-on, interactive environment to students around the world. TIE is a non-profit foundation sponsored by the National Aeronautics and Space Administration (NASA) and developed through the efforts of numerous volunteers, businesses and supporting organizations.
