Surface Forms

telescope singular
telescopes plural

Morphology

telescope = scope (semi-transparent) = tele + scope

The classical combining form 'tele-' plus 'scope' yields the meaning 'far-seeing instrument', which is recoverable but still learned as a specialized scientific term.

Etymology

Telescope comes from Greek parts tele- 'far' and -scope 'to look'. So a telescope is literally a tool 'to look far', which is why it makes distant things appear closer.
