The Dobsonian Telescope: A Practical Manual for Building Large Aperture Telescopes

This book tells how you can build a state-of-the-art Dobsonian telescope using readily available materials and supplies. Every step of construction is detailedin photographs and diagrams, and the underlying ideas are carefully explained. As a result of this three-year collaboration between authors David Kriege and Richard Berry, experienced and well-known telescope makers, you now have the opportunity to build a high-performance telescope from 14 inches to 40 inches aperture based on the thoroughly tested designs described in this book. The Dobsonian telescope takes its name from the astronomer/philosopher John Dobson, who introduced the concept of inexpensive, large-aperture telescopes to astronomy. Amateur astronomers at the time were so amazed that a telescope builtfrom simple, inexpensive materials performed so well that they could hardly believe their eyes. As home-built Dobsonians started showing up at star parties across the nation and people saw what Dobsonians could do, the word spread. In just a few years, the Dobsonian revolution swept the world. Since those early telescopes, Dobsonians have improved dramatically. An entire generation of amateur telescope makers contributed their best insights and refinements to Dobson's original design. Today's Dobsonians are larger, lighter,and more precise than ever before. For example, it is possible to build a telescope of 20 inches aperture that is compact enough to transp


The Complete Guide to Building Your Own 8-inch Telescope

I've written a book on how to build a telescope just like the one I did so anyone can do it. Every step and every piece is covered in great detail so you can actually build a powerful telescope much more powerful than the one's typically found in department stores. The optics are larger with greater light-gathering power and resolution, enabling you to observe fainter stars, nebulae, and galaxies, and to see finer detail on planets. The high magnifications advertised with department store telescopes are actually useable with this telescope. The eyepieces are larger with a bigger window for the eye to look into, not something you must squint and strain to see anything. The mounting is very rigid and stable, not like the flimsy tripods that move and vibrate to the point you have to move your head around trying to keep up with the bouncing image. The simple design makes the instrument able to be set up in seconds anywhere you bring it. If you follow the instructions in the order given it's almost impossible to fail. The large optics gather 500 times more light than the unaided eye, permitting stunning views of the universe. Amaze your family and friends with the achievement of making a powerful telescope that will yield a lifetime of beautiful views of the heavens. This would make a great parent-child project that would prove very rewarding. Be prepared for sighting celestial objects like you've never seen them before with this truly powerful 8-inch reflecting telescope.

Orion Three-Fan Cooling System for Convex-Back Dobsonians

This time-saving cooling system features three fans which have been custom designed to fit the Orion XX14g GoTo Dobsonian primary mirror cell. All three small fans work in tandem to help reduce the amount of time needed for the telescope to reach thermal equilibrium with the ambient air temperature of your observing location. You'll enjoy peak performance from your XX14g GoTo Dobsonian without having to wait as long for the air inside the telescope to cool down to the same temperature as your stargazing site. Consisting of three 12-volt DC, 0.12A fans which are wired in parallel, the Orion Three-Fan Cooling System for Convex-Back Dobsonians features a single 35" long power cable splitter for convenient use. Each fan boasts 33.4 CFM (cubic foot per minute) air flow to help significantly accelerate cooling of your Dobsonian telescope's optics. The fans operate quietly without vibrating, and they mount easily in threaded holes on the the XX14g primary mirror cell with included hardware. For best results, run the Orion Three-Fan Cooling System prior to using the reflector telescope. You can also use the cooling fans intermittently between observations to compensate for any ambient temperature changes that may occur. Power is supplied using the included battery holder which accepts 8 D-cell batteries (batteries not included). Since the Three-Fan Cooling System current draw is a low 0.36 amps, a full battery holder with 8 D-cells will provide over 24 hours of use.


Celestron 21024 FirstScope Telescope

In 1609, world-renowned Italian scientist, Galileo Galilei, introduced an elementary telescope to the growing astronomy community, which sparked interest into the mysterious night sky for centuries to come. Four centuries later, in celebration of the International Year of Astronomy 2009, Celestron offers the portable FirstScope Telescope. The FirstScope pays tribute to Galileo Galilei and many of history's most notable astronomers and scientists by displaying their names around the optical tube. Honoring the contributions of these men and women, who brought us one step closer to understanding the universe around us. The FirstScope is a wonderful keepsake for anyone interested in astronomy. This quality Dobsonian style telescope features a 76mm aperture reflector optical tube. FirstScope is an ideal entry-level astronomical telescope. It is very easy to observe with; you simply navigate the night sky by moving the tube in the direction of the desired object, making the viewing experience a snap! The compact design makes it easy enough to take with you on your next outdoor adventure. FirstScope is also stylish enough to be a decorative fixture on your bookshelf or desk.
