The First Telescope
It is a far cry from the giant telescope which is now being constructed in the Uitcd States, with its 20-ton reflecting mirror of 200iu diameter, to the little instrument made by Galileo and first used in 1610. But this refracting telescope of “the Starry Galileo” was the first practical telescope ever made (says the Manchester Guardian). It magnified 30 times, and through it Galileo first saw the mountains on the moon, the satellites of Jupiter, and Saturn’s rings. It. is truo that he had previously made a small instrument out of an old organ pipe and two spectacle lenses, but as that only magnified three times it was not exactly effective.
