Galileo Galilei was an Italian philosopher, astronomer and mathematician (d. 1642). Among his many contributions, he was able to discover Jupiter's four largest satellites, spots on the Sun, phases of Venus, and the hills and valleys of the Moon. He was able to do these things with his cannocchiale, or telescope, that he first built in 1609.

What is a Galilean Cannocchiale, telescope or monocular?

Galileo used his telescope to view distant objects, and it doesn't get much more distant than space. But just what is this telescope? Galileo's telescope in its simplest form is comprised of two lenses: the objective lens (the lens that forms the image) and the ocular (eye piece). Placed in front of the focus is a divergent lens, and with his, an upright image appears.

It looks something like this:
