Galileo refined the early telescopes to produce instruments with better magnification and in 1609 he took the first recorded astronomical observations with a telescope. Indeed, the first use of the word telescope, which is constructed from the Greek words ‘tele’ meaning ‘far’ and ‘skopos’ meaning ‘seeing’, is associated with Galileo’s instrument.
Who was the first person to use a telescope?
His application was refused and, in the resulting publicity, the Italian astronomer Galileo Galilei (1564-1642) became aware of the device. Galileo refined the early telescopes to produce instruments with better magnification and in 1609 he took the first recorded astronomical observations with a telescope.
How do you calculate the magnification of a Galilean telescope?
To calculate the magnification of a Galilean telescope, we divide the focal length of the objective by the focal length of the eyepiece. So, if the focal length of the objective is 200 cm and the focal length of the eyepiece is 10 cm, the magnification of the telescope would be 20. Update 22 November 2020
What can you see at the Galileo Museum?
The Museum holds exhibitions on Galileo’s telescope and the observations he made with it. The displays consist of these rare and precious instruments – including the objective lens created by the master and the only two existing telescopes built by Galileo himself.

What did Galileo discover about the phases of Venus?
With his observations of the phases of Venus, Galileo was able to figure out that the planet orbits the Sun, not the Earth as was the common belief in his time. Curious about the Sun, Galileo used his telescope to learn more. Not knowing that looking at our very own star would damage his eyesight, Galileo pointed his telescope towards the Sun.
