Because it captures large amounts of light, a Dobsonian telescope is an ideal workhorse for deep-sky enthusiasts and a great instrument for getting highly detailed views of our planetary neighbors.
  Although the size of these large aperture telescopes can appear daunting, the truss tube structure is made from aluminum for maximum rigidity with a minimum of mass. These telescopes can be broken down and transported easily even in small cars and reassembled within minutes without tools. The combination of big altitude wheels and an optimized aluminum-sandwich construction allows for small movements even at high magnifications.
  Each of our truss tube Dobsonians comes with a 2” dual-speed focuser with helical gearing and a soft light baffle to limit interference from stray light sources.

  As part of our weekend celebration of astronomy, you can take advantage of significant savings on all truss tube Dobsonians: 

* Save $250 on the 10-inch truss tube Dobsonian 

* Save $400 on the 12-inch truss tube Dobsonian

* Save $600 on the 16-inch truss tube Dobsonian 

* Save $1,100 on the 20-inch truss tube Dobsonian*

(*Please note the 20-inch model is a special order item with an estimated delivery time of 90 days.)  

  The Galileoscope is a high-quality telescope kit created by astronomers, optical engineers, and science educators as a cornerstone project for the 2009 International Year of Astronomy. Since its creation, hundreds of thousands of kits have been distributed in more than 100 countries, which has promoted astronomy and science education worldwide.

  While assembling the kit, which requires no tools or adhesives, users can learn basic optical concepts, including how lenses form images. With the completed 2-inch-diameter, 25- to 50-power telescope, observers can enjoy sharp views of lunar craters and mountains, Jupiter and its moons, and Saturn’s rings. The kit is augmented with free, standards-based optics-education and observing activities, available in multiple languages. The Galileoscope is suitable for learners of all ages from 8 to 88!
