Telescopes come in all shapes and sizes; the Hubble Space Telescope weighs an amazing several tons. There are two types of telescopes: the refractor telescope and the reflector telescope. The refractor telescope uses glass lenses in its anatomy, while the reflector telescope uses mirrors instead of lenses.

The objective lens (in refractors) or primary mirror (in reflectors) collects a lot of light from a distant object and brings that image to a point or focus . An eyepiece lens takes the bright light from the focus of the objective lens or primary mirror and "spreads it out" (magnifies it) to take up a large portion of the retina.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
