Albert Einstein's long-lost telescope, forgotten for decades in a Jerusalem storage shed, goes on display this week after three years and $10,000 spent restoring the relic.

The old reflecting telescope is cumbersome by modern standards, but a demonstration for The Associated Press showed it still works well enough to see five of Jupiter's moons and stripes on the surface of the huge planet.

The legendary physicist who famously theorized relations among energy, speed and mass received the telescope in 1954, the year before he died. It was a gift from a friend named Zvi Gizeri, who probably made it himself, said officials at the Hebrew University in Jerusalem where the public will be able to view the telescope starting Thursday.
