Neither Newton nor Galileo invented the telescope. It was developed independently by various dutch optics makers (Lippershey submitted the first patent). Galileo's first telescope was dutch-made, and he made useful improvements to the initial retractor design. Newton did invent the reflecting telescope (the particular design is now called a Newtonian Telescope). Further improvements to the reflector design were made by Cassegrain and others made improvements to the manufacturing process, greatly improving the mirror quality.
A refracting telescope uses a lens as the main objective, while a reflecting telescope uses a mirror. The objective is the component that focuses the light. Reflector telescopes are the most common nowadays, as they do not suffer from chromatic aberration (light splitting due to refraction) and can be built in very large diameters.
