A telescope is an instrument esigned for the observation of remote objects and the collection of electromagnetic radiation. The first known practically functioning telescope is credited to the German-Dutch lensmaker Hans Lippershey in 1608. The name "Telescope" (from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing') was a name given to Galileo Galilei's instrument for viewing distant objects. The name was invented by an unidentified Greek poet/theologian, present at a banquet held in 1611 by Prince Federico Cesi to make Galileo Galilei a member of the Accademia dei Lincei. "Telescope" can refer to a whole range of instruments operating in most regions of the electromagnetic spectrum.
