Detailed explanation-1: -Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens.
Detailed explanation-2: -The basic tool that Galileo used was a crude refracting telescope. His initial version only magnified 8x but was soon refined to the 20x magnification he used for his observations for Sidereus nuncius. It had a convex objective lens and a concave eyepiece in a long tube.
Detailed explanation-3: -Galilean telescope, instrument for viewing distant objects, named after the great Italian scientist Galileo Galilei (1564–1642), who first constructed one in 1609.
