what were two differences between their telescopes? All I know so far is that Galileos turned things upside down, and was therefore used for astronomical researching. What was Newtons used for and what were the TWO differences between their telescopes?

Newtons was a reflectong scope. It used mirrors.
Galileo used lenses to make a refracting scope
Newtons was bigger
Newton actually invented his
Galileos was made earlier

Galileo's telescope does not turn things upside down because he used a negative lens for the eyepiece. Modern astronomical telescopes use a positive eyepiece and do turn things upside down.
Galileo's telescope was a refractor, using only lenses to focus light.
Newton's telescope was a reflector, using a curved mirror as the objective lens, although still using a lens for the eyepiece. To avoid the observer having to block the light entering the telescope with his head, light is directed to an eyepiece to one side by a small flat mirror.
