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 50 mm (2.0 in) and a relatively long focal length of 500 mm, for a focal ratio of f/10. [2]

The first astronomer to publicly support Galileo's findings was Johannes Kepler, who published an open letter in April 1610, enthusiastically endorsing Galileo's credibility. It was not until August 1610 that Kepler was able to publish his independent confirmation of Galileo's findings, due to the scarcity of sufficiently powerful telescopes. [17]
