It was developed for the International Year of Astronomy 2009. It is meant to be an inexpensive means by which millions of people can view the same things seen by Galileo Galilei, such as the craters of Earth's Moon, four of Jupiter's moons, and the Pleiades. The small telescope has an aperture of and a relatively long focal length of 500 mm, for a focal ratio of f/10.
