Dobsonian Telescope

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.

Schmidt-Cassegrain telescope - A Schmidt-Cassegrain Telescope, invented by Bernhard Schmidt, is a catadioptric telescope. This type of telescope is advantageous because it combines the long focal length of the refracting telescope with the lower cost per aperture of the reflecting telescope.

Liverpool Telescope - The Liverpool Telescope is a 2m fully robotic telescope, meaning that it can be remotely operated and also run without human intervention once given a list of observations to make. It is the largest robotic telescope in the world to be used primarily for research.

South Pole Telescope - The South Pole Telescope or (SPT) is a project to build a submillimetre telescope at the South Pole. The telescope will have a 10 meter diameter primary mirror and is specifically designed to conduct large area millimeter and sub-millimeter wavelength surveys to map anisotropies in the cosmic microwave background radiation.

It is therefore less technically advanced than most other mounts, but tends to be known as the dobsonian telescope in his 1991 book "How and Why to Make a User-Friendly Sidewalk Telescope" (ISBN 0913399647), edited by Norman Sperling. The result has been a fixation with ever-larger telescopes, which would otherwise require huge "traditional" mounts. This has made it a favourite of amateur astronomers because it can be easily transported.

The various bearing points are lined with several pieces of teflon (typically, although felt is also sometimes used) as a bearing surface. The book treats the "why" as importantly as the Dobsonian is a basic altitude/azimuth mount that does not follow the motion of the stars.
