"Sky Challenger" 1978
This star finder was produced by the Lawrence Hall of Science and published by the University of California Regents in 1978. It was intended for children.
It came with six different wheels that are all present here. Each of the wheels was intended as a different activity. I also have a star clock and a newsletter that was produced by the same group.
Pictured here are the front and back each of the wheels.
