| What
is a "Telescope"? |
 |
 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. |

In
general, there are two kinds of telescope systems.
One is the Optical Telescope. This is our main manufacturing
base. The other is the radio telescope, which is used
for National & Scientific research . We manufacture
only a few of these.
