What is the StarLab?
The Classic Starlab® System is a teaching aid geared toward astronomy. In brief, it is composed of a dome made out of opaque vinyl, and a projector, which displays images on the inside of the dome. The projector produces bright light, which is fully adjustable by the user. The images are produced using Starlab® cylinders, which are made out of film. The film used is entirely opaque, except for the portions where the images are. In this way, all the light from the projector is blocked except what is needed to create images. A major advantage of the film is that it affords nearly infinite contrast ratios.
