Galileo Galilei used a telescope to make detailed observations of the stars and planets. He is most well known for suggesting that the Earth revolves around the Sun, and not the other way around.

Galileo Galilei is best known for his work in astronomy and physics, particularly for being the first to use a telescope to study the stars and planets. His observations and experiments challenged prevailing beliefs about the nature of the universe and laid the foundation for modern science.
Galileo did not discover any new constellations. Instead, he made important observations about the existing constellations and their movements in the night sky, using his telescope to study the stars and planets.
a telescope because if you never heard of the Hubble telescope that is like the international telescope.
Tycho Brahe was responsible for making detailed astronomical observations that ultimately supported Nicolaus Copernicus' heliocentric theory. Brahe meticulously recorded the positions of planets and stars without the aid of a telescope, which was not invented until after his time. His data was later used by Johannes Kepler, who formulated the laws of planetary motion. Brahe's life ended in 1601 under mysterious circumstances, with theories ranging from kidney failure to poisoning.

Lots of people did, and still do. Astronomers do that all the time.
