Telescopic means able to see far off, or made of sliding sections. A telescopic sight, a telescopic ladder, telescopic handle.
The sliding sense is the more useful in ordinary life, since a telescopic pole collapses into itself the way the tubes of an old telescope did. A telescopic sight is a small telescope mounted on a rifle.
