Stars are so far away that any amateur telescope will only show them as brighter points of light. With a telescope, you will see fainter stars, but again they are points of light. You can see what are called extended objects like the moon and planets. But to see the planets properly you need high magnification.
The best way to get familiar with telescopes is to join a local astronomy club if there is one in your area. Y(ou can look through many types of telescopes to make an educated decision on what you need for yourself.
