The kind and extent of equipment needed is a function of the size of a planetarium, its self-defined tasks, the contents of its shows, and the budget available.
Modern planetarium equipment offers a multitude of presentation capabilities. The sky projected by the planetarium machine takes pride of place. It can be assisted by projectors for special effects, slides, videos and movies. In new and upgraded planetarium theaters fulldome displays takes center stage as well.
A planetarium show would be incomplete without high-quality sound reproduction. All projection, illuminating and sound reproduction systems have to be adapted to the special conditions provided by a spherical projection surface, and all systems need to have automatic control. | |
