Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.

The popular answer to this question would be Galileo. However, contrary to popular belief Galileo did not invent the telescope. He built his own telescope about a year after their initial creation and later made significant improvements.
Galileo
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
Copernicus proposed the theory of a heliocentric model while Galileo improved the telescope, studied Jupiter's moons, and supported the heliocentric model
Galileo Galilei, the Italian scientist and mathematician, wrote the book The Starry Messenger in 1610. The book described his observations made using a telescope and supported the heliocentric model of the universe. It was later condemned by the Catholic Church for contradicting the geocentric view supported by the church at the time.
I suspect the answer you're looking for is Galileo Galilei. It just has two problems: Galileo didn't "invent the telescope", nor did he "develop a heliocentric view of the universe." The telescope was invented in the Netherlands; Galileo simply improved on it and was probably the first to apply it to astronomical observations instead of just looking for distant ships. Also, Copernicus is (properly) credited with the heliocentric view; Galileo's observations supported this, but he didn't come up with it.
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
Galileo Galilei died on January 8, 1642. He was an Italian astronomer who made many discoveries and observations through the use of a telescope, including the moons of Jupiter and the observation of sunspots. He also supported the heliocentric theory. He was born in 1564.
