Disc for Sega Toys Homestar Pro La Silla Scenic

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 disc shows the sky above La Silla, in the Chilean Andes at an altitude of 2,400 metres. The European Southern Observatory (ESO) operates several observatories here. The red colour on the slide is caused by airglow. This is a glow in the upper atmosphere caused by cosmic radiation.

However, the foreground does not show the La Silla observatories, but the Atacama Large Millimeter/submillimeter Array (ALMA), also located in Chile's Atacama Desert.

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.
