A claim will be made 37 years later by another Dutch spectacle-maker that his father, Zacharias Janssen, invented the telescope. [17] A replica of Galileo's telescope. 1609 — Galileo Galilei makes his own improved version of Lippershey's telescope, calling it a "perspicillum".
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby."

By using two types of glass for the two lenses this gets compensated to some degree, resulting in a sharper and clearer image. Depending on the configuration, 4, 6 or 8 lenses are used. The 4-lens configuration results in a telescope in some ways similar to Galileo's, with 17× magnification and a very small field of view.
Galileo Galilei was an Italian scientist who is sometimes referred to as the "father of modern observational astronomy". [16] His improvements to the telescope, astronomical observations, and support for Copernicanism were all integral to the Copernican Revolution.

The manuscript is largely in Galileo's handwriting, and the sections in Guiducci's hand have been revised and corrected ...
Directed by Kris Koenig, it chronicles the history of the telescope from the time of Galileo and features interviews with leading astrophysicists and cosmologists from around the world, who explain concepts ranging from Galileo's first use of the telescope to view the moons of Jupiter, to the latest discoveries in space, including new ideas ...
The celatone was a device invented by Galileo Galilei to observe Jupiter's moons with the purpose of finding longitude on Earth. It took the form of a piece of headgear with a telescope taking the place of an eyehole.
