The Galileoscope is a high-quality telescope kit created by astronomers, optical
engineers, and science educators. Because it is produced and distributed by
volunteers, it is available at low cost to support science education worldwide.
With some 225,000 kits already in use by teachers and students in more than
100 countries, the Galileoscope has been designated an International Year of
Light cornerstone project, with the goal of distributing an additional 100,000
telescopes during 2015.
While assembling the kit, which requires no tools or adhesives, students learn
basic optical concepts, including how lenses form images. With their completed
2-inch-diameter, 25- to 50-power telescope, they enjoy sharp views of lunar
craters and mountains, Jupiter and its moons, and Saturns rings. The kit
is augmented with free, standards-based optics-education and observing activities,
available in multiple languages. These can be used to teach science and the
process of science at all grade levels.
Each Galileoscope kit assembles in minutes and includes the following:
- 50-mm f/10 achromatic objective lens, glass
- 25x achromatic eyepiece lens pair, plastic

- ¼-20 mounting nut, metal
- Assembly instructions
- Sun-warning sticker
- Size: 19½ by 6¼ by 4¼ inches (49.5 by 15.9 by 11.1
- Weight: 2.6 lb (1.2 kg).
