This is a projection screen for Sega Toys Homestar Pro Original home planetarium. It extends the possibilities of your planetarium! The disc is manufactured to a very high quality and specially designed for use with the Homestar Pro.
The 'Disappearing Continent' disc shows an unfamiliar view of the famous North American nebula in the constellation of Cygnus. The photo was taken with NASA's Spitzer space telescope and shows this region of the night sky in infrared light. As longwave infrared can penetrate the dense dust of the nebula, the North American nebula disappears and the underlying structures become visible.
What does 'Scenic' mean? These discs consist of two parts. The main disc shows the actual theme. There is also a second disc showing a foreground - for example trees. When the motor is on, only the main dial turns, while the foreground is stationary. This combination results in an attractive effect.
The first figure shows the disc with the main theme, the second figure shows the combination of the main theme and the foreground.
