ATTENTION: 1. The light source of stars and nebulae is strong, so eyes should not look directly at the light source. 2. The brightness of the stars (i.e. laser brightness) is affected by the ambient temperature and time of use. When the ambient temperature is hot or the power - on time is longer, the brightness of the laser will decrease due to the heat of the light source. At this time, just turn off the power and let the laser emit. The heat dissipation of the device (heat dissipation time usually takes more than 15 minutes) and then turn it on to restore the brightness. 1. The head and body of the astronaut are connected together by magnets, and the direction of the head can be adjusted. Do not stretch the astronaut's head and body forcefully, otherwise the wires may break due to stretching.
