What is a "Telescope"?

telescopes knowledge   A Telescope is an instrument that gathers light and allows it to be magnified by way of an eyepiece, or ocular. History points the invention of the telescope to Hans Lippershey, a Dutch spectacle maker. Later, in the early 1600's, it was re-invented by Galileo. On the night of April 14, 1611, a banquet was held in his honor outside Rome. Galileo showed the guests his instrument and let them see his discoveries. An unidentified Greek poet-theologian happened to be present and he proposed a name for the instrument, one borrowed from ancient Greece. It was quickly accepted and the host, Federico Cesi, then officially christened Galileo's instrument, "the telescope." There are many different styles of telescopes, but the two most common are the Newtonian Reflector, named after Isaac Newton, and the Refractor. Cassegrains, Maksutov's, and variations of both are styles that are very popular amongst both professional and amateur astronomers alike.
