Transform your darkened room into a cosmic light show and explore the universe with the Deep Space Home planetarium and projector. This projector-planetarium features its own stand, and the main body of the unit is rotatable, allowing you to use either the projector or the planetarium. The planetarium has two domes, one projecting star patterns and the other constellations onto ceilings and walls. Place the black star or constellation dome into the slots at the top of the unit, gently twist it to secure the dome in place, turn on the dome projector setting, and watch as the images rotate around the room. Unscrew the domes to remove them. Add a dome with a night light, and the deep space becomes a cool night light with rotating stars and constellations. Operates on 3 AA batteries (not included).
