Product details Henry Kater's telescope
Henry Kater's telescope
Telescope used by Henry Kater for pendulum observations. Geodesist and metrologist Henry Kater (1777-1835) invented Kater's pendulum in 1817 which enabled the strength of gravity to be determined. This sight was used to view the pendulum during observations in order to avoid parallax error.
