Guide to the Stars (Wheel)
David H. Levy & Ken Graun
This 16-inch diameter plastic Guide to the Stars chart is a ''map'' to help you identify the constellations. You simply dial-in your observing time and date to find the set of constellations visible in your sky (this is accomplished by rotating the clear top piece). This chart can be used for latitudes 30 to 60 degrees North, which covers the US and Canada. Although this chart is designed for beginners, it finds use with seasoned amateur astronomers. This type of round star chart is often called a planisphere because it takes a set of stars on a sphere and plots them on a flat surface.
