Abstract
An optical planetarium includes a projector configured to project images of stars; a diurnal-axis support mechanism configured to allow the projector to rotate about a diurnal axis; a latitude-axis support mechanism configured to allow the projector to rotate about a latitude axis that is orthogonal to the diurnal axis; an azimuth-axis support mechanism configured to allow the projector to rotate about an azimuth axis that is set vertically; and a latitude-axis inclination angle changing mechanism configured to allow an angle between the latitude axis and a horizontal plane to be changed within a predetermined range.
