The use of 532NM green laser pointer
Obviously, the intensity of the laser radiation power reflecting the laser radiation power through the stimulated laser beam is too high, which will cause photochemical and thermal damage to the body. It is still in the development stage, especially for children, when it is used as a laser pointer. When the eyes and skin turn blue, it can cause more serious consequences. Wu introduced that when the laser visual damage and its intensity are proportional to the exposure time, the maximum green 500mW laser pointer, the longer the exposure time, the more serious the optical damage. Why do your eyes burn?

Application
In any case, in order to display the constellation, I would recommend a 5000mW green Laser pointer. I can't say too much about the performance. I think 5 mW should be enough. In some astro shops, laser pointers of 1000MW and up to 15 mW are available. If you want to be completely exaggerated, you can buy a laser pointer with more than high performance. That always brings a brighter beam, but it also makes the whole thing more dangerous!
