in 1609 Galileo made first telescopes
Galileo made his first telescope in 1609, modeled after telescopes produced in other parts of Europe that could magnify objects three times. He created a telescope later that same year that could magnify objects twenty times. With this telescope, he was able to look at the moon,

The telescope was invented by Hans Lippershey, a spectacle maker from the Netherlands, in 1608. However, another spectacle maker and astronomer, Galileo Galilei, was the first to use the telescope for astronomical purposes in 1609.
By 1609 Galileo had a telescope that magnified 20x
A telescope.
Yes they where by Galileo in 1609.
He improved on the existing telescope around 1609
The sources of Galileo is he wasn't the inventor of the telescope,but he was the first to use the telescope. Also he improved the telescope making an object look about 20 times bigger.Also,he made it magnify 3 times as much as before made this improvement in 1608-1609.
Galileo made his telescope in 1609, based on descriptions of instruments made in the Netherlands a year earlier. Despite what a depressingly large number of people would have you believe, he did not invent the telescope (though his was arguably an improvement upon the earlier ones).
The telescope was first used by the Italian astronomer Galileo Galilei in 1609. Galileo made significant observations of celestial bodies such as the moon, Jupiter, and Venus using his telescope, which played a crucial role in revolutionizing our understanding of the universe.
