Many beginners make the mistake of buying telescopes that offer high power with little light gathering aperture. This results in poor image quality, dim image brightness, and a very narrow field of view. Seasoned astronomers will tell you to learn the sky with binoculars and then look for a good telescope.
Most serious amateurs have both.
