A laser pointer that can point to constellations
This high-power laser pointer provides 20 milliwatts (mW) of power and limits its sales. Many regions limit consumer laser intensity to less than 5 milliwatts, on the grounds that safety issues are the main reason. This laser pointer overcomes this limitation because it produces a beam that is much stronger than many consumer models. The purple beam can reach a distance of more than 200 meters. As a general rule of thumb, please note that lasers lower than 200mW cannot provide enough heat to burn, but lasers higher than 200mW generate enough heat to be regarded as hot lasers. This is very important. If you are looking for a laser that can illuminate matches, etc., make sure that its power is at least 200mW.

Perhaps one of the most classic laser pointer products is the Astronomy-Astronomy Laser Pointer. Many laser enthusiasts and fanatics buy high powered laser equipment and do night shifts by themselves, with family or friends. Laser pointers are of course very useful for various astronomical actions. Before looking at the stars, they will ask you to choose one. Since the human eye is most sensitive to green, green laser equipment is quickly becoming known to many buyers. In addition, the output varies depending on the type of green laser pointer. For astronomers, lasers above 50 mW are suitable for observing stars and other celestial bodies. And with the development of laser pointers in the entire field of astronomy, experts invented special astronomical lasers.
