The sidereal clock

With the help of the sidereal clock, the local time (= solar time) can be read at night from the position of the constellation Big Dipper in relation to the pole star. The device consists of two rotating discs, one above the other, with a pointer and a hole in the middle. The date is set on the lower disc. Then the pole star is aimed through the hole and at the same time the pointer is set to the pole pointer of the Big Dipper. In this way, the time can be read on the upper disc. If it is too dark, you can even find the time by touching it with your fingertips.

The star clock is easy to build and is an excellent teaching aid for secondary schools.
