The Galileoscope™: An IYA2009 Cornerstone Project
The Galileoscope™ is a high-quality, low-cost telescope kit developed for the International Year of Astronomy 2009 by a team of leading astronomers, optical engineers, and science educators. No matter where you live, with this easy-to-assemble, 50-mm (2-inch) diameter, 25- to 50-power achromatic refractor, you can see the celestial wonders that Galileo Galilei first glimpsed 400 years ago and that still delight stargazers today. These include lunar craters and mountains, four moons circling Jupiter, the phases of Venus, Saturn's rings, and countless stars invisible to the unaided eye. As of August 10, 2009, the kit is priced at U.S. $20 each plus shipping for 1 to 99 units, or U.S. $15 each plus shipping for 100 units or more (see below).
