The reason why the star laser pointer was chosen
First of all, the most obvious use of a laser pointer is to point! You can use lasers to accurately show your friends the night sky, especially when talking with a group of people. Be sure to follow the safety tips below. Also, only use laser pointers that are not "always on" (ie, what you need to press to make them work). If you want to report an object to a friend or other member of the astronomy club, please make sure that you cannot see nearby aircraft, and then press the laser to point the beam exactly where the object was found. Once the other party knows where you are aiming, immediately turn off the laser again.

This is a fast and efficient way to provide a night sky tour for beginners and provide veterans with pointers to the sights you are looking for. Precautions have shown that the green Laser pointer can point to the stars very well at night. The human eye responds to different colors, and the peak of color numbness is green. The green laser cannot be aimed at your eyes and has a very narrow beam, which can be seen at a long distance due to night vision. This is why the red laser cannot interfere with the night vision of astronomical sighting. The green light emitted by the atmosphere is 10 times that of red light. In the eyes of human eyes, green lasers are much better than red lasers. 532nm green is more sensitive, so the human eye is more sensitive than green and red lasers. The low-power green laser pointer is always the right choice for astronomical research and pointing.
