In order to ensure that the planetarium can have better applicability, the projection angle and projection position of the projector can be adjusted. Now a rotating planetarium is proposed, which can synchronously rotate and adjust the projection position of multiple groups of projectors, so that the star image projected on the sky screen can be rotated, which is convenient for viewers to watch the star image and improves the viewing experience. The projector can be adjusted in angle so that the projection area of ​​the projector can be adapted to the planetarium sky screen. The overall height and angle of the planetarium sky screen can also be adjusted, so that the sky screen can display the star image at a suitable height and angle, which is suitable for viewers of different heights.
