Galileo and the telescope - Explaining Science
2018年3月13日 · Galileo turned his telescope to the Milky Way and discovered that it consisted of a vast number of stars, each too faint to be seen individually with the naked eye. When viewed from Earth these stars are so closely packed together they appear to be clouds.
Galileo's telescope - How it works
The Galilean telescope (fig. 1) consists of a converging lens (plano-convex or biconvex) serving as objective, and a diverging lens (plano-concave or biconcave) serving as eyepiece. The eyepiece is situated in front of the focal point of the objective, at a distance from the focal point equal to the focal length of the eyepiece.
