When did the telescope become a tool for astronomers? Who was the first to use the telescope? Who was the last astronomers without a telescope?

Hans Lippershey (whose last name is
sometimes spelled without the letter
“s”), a Dutch eyeglass manufacturer,
is most often associated with the
invention of the telescope. Lippershey
was awarded a patent for his device in
October 1608 by the parliament in the
Netherlands.
historians generally say that Galileo was the first person to use a telescope. In 1609, Galileo observed the skies through a telescope. Hearing about Hans Lippershey’s new invention, he was the first person to use this telescope.

Galileo was the first person to use a telescope for astronomy in 1610. But other astronomers continued to do work without telescopes for many years after that.

The earliest known working telescopes appeared in 1608 and are credited to Hans Lippershey. Among many others who claimed to have made the discovery were Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece. Galileo used this design the following year. In 1611, Johannes Kepler described how a telescope could be made with a convex objective and eyepiece lens and by 1655 astronomers such as Christiaan Huygens were building powerful but extremely large and unwieldy Keplerian telescopes with compound eyepieces. Hans Lippershey is the earliest person documented to have applied for a patent for the device. “Astronomers” that didn’t use telescopes merely charted stars and watch celestial movements, and the last of those were the astronomers before and around the time when the telescope was invented.

Exactly 400 years ago this year, in 1609 — that’s why 2009 is the International Year of Astronomy, The first to use the telescope for astronomy were Galileo Galilei and Thomas Hariot. The last major astronomer before the telescope was Tycho Brahe.

It was first used by Galileo around 1608. But it became a tool in October of 1608 by Hans Lippershey.

Hans Lippershey, in 1608, invented the telescope. but Galileo was one the that used it to find his discoveries.
