The Sky at Night

Name: The Sky at Night S36E9 - The First Telescope
Uploaded: 1992-08-16
Description: It is usually accepted that the first telescope was made in 1608. But new evidence shows that the first reflector was made in England, by Leonard Digges , many years before. In this programme Colin Ronan joins Patrick Moore to explain the principle, and to show the first "working" Digges-type telescope to have been made for more than 400 years.
