There are two: Tycho Brahe, whose detailed observations aided Kepler's discoveries of the laws governing the planetary orbits, working in the 16th century before the use of telescopes, and William Herschel, whose systematic catalog of thousands of non-stellar objects is essentially still used today, working roughly 200 years later with telescopes of his own design and manufacture. Since nearly all serious astronomy, even among amateurs, is now done with cameras of various sorts, no one is likely to match their achievements with the naked eye.
Although Copernicus should really be known as the first astronomer, Galileo Galilei was known as the father of modern astronomy, He was born on February 15, 1564 in Pisa, Italy. He constructed the first thermoscope and significantly improved the existing telescope, which he used to discover the mountains on the Moon, four satellites of Jupiter and he also defined the Milky Way`s structure. As a prominent physicist, he set up numerous theories, which amount to the corner stone of many research projects. He established ballistics, a category of physics which studies the trajectory of missiles, and he also determined the laws of free fall. After Galileo pointed out that Copernicus` Heliocentric theory was the only right one, the Vatican inquisition imprisoned him in Rome and he was forced to forsake his studies and spend the rest of his life in prison. Still, as Pope Urban VIII insisted, the prison sentence was reduced to house arrest. Some of Galileo`s works were found on the Vatican list of banned books. He wrote a total of 16 works. Even though he forsake his teachings, supposedly, he uttered "And yet it still moves" before his death, keeping the solar system in mind. He died under house arrest in Florence, at the age of 78, almost completely blind. In his honour, the Jupiter exploration craft and European satellite navigation systems were called Galileo.

No. But yes. Yeast is a microbe but it is visible with the naked eye
no
Something that is so small that you cannot see it with the naked eye but must use a microscope to observe it
No
Because, it is too small to see with the naked eye.
The term "naked eye" means that there is nothing helping the eye to see. for example, if you are using glassess or a telescpoe, then you are not using the naked eye.
