ONLINE ETYMOLOGY DICTIONARY:

telescope (n.)

1640s, from It. telescopio (used by Galileo, 1611), and Mod.L. telescopium (used by Kepler, 1613), both from Gk. teleskopos "far-seeing," from tele- "far" (see tele-) + -skopos "seeing" (see -scope). Said to have been coined by Prince Cesi, founder and head of the Roman Academy of the Lincei (Galileo was a member). Used in English in Latin form from 1619.

tele-

word-forming element meaning "far, far off," from Gk. tele-, combining form of tele "far off, afar, at or to a distance," related to teleos (gen. telos) "end, goal, result, consummation, perfection," lit. "completion of a cycle," from PIE *kwel-es- (cf. Skt. caramah "the last," Bret. pell "far off," Welsh pellaf "uttermost"), from root *kwel- (see cycle).

-scope

word-forming element indicating "an instrument for seeing," from L.L. -scopium, from Gk. -skopion, from skopein "to look at, examine" (see scope (n.1)).

scope (n.1)

"extent," 1530s, "room to act," from It. scopo "aim, purpose, object, thing aimed at, mark, target," from L. scopus, from Gk. skopos "aim, target, watcher," from PIE *spek- "to observe" (cf. Skt. spasati "sees;" Avestan spasyeiti "spies;" Gk. skopein "behold, look, consider," skeptesthai "to look at;" L. specere "to look at;" O.H.G. spehhon "to spy," Ger. spähen "to spy"). Sense of "distance the mind can reach, extent of view" first recorded c.1600.

scope (n.2)

"instrument for viewing," 1872, abstracted from telescope, microscope, etc., from Gk. skopein "to look" (see scope (n.1)). Earlier used as a shortening of horoscope (c.1600).
