Safe use of astronomical green laser pointer
Star pointers Pointers should be used with caution. This is an application that requires a relatively powerful laser so that the observer can see the beam tree (not just the end point). In addition, the beam points to bright objects in the sky. External laser users should be aware that these bright and sharp objects may float in the air. Can be used safely for astronomy education

Rather than hundreds of feet, the beam can pose a danger to the pilot for miles. The strongest beam in the photo can cause severe glare at 2 miles (the pilot cannot see the other side of the light), but the risk of distraction is 22 miles! Keep the beam away from stars or unknown stars along the visible light path or invisible light. In this way, in daily life, it is a familiar item with multiple uses. At the same time, if you don't know the correct choice and method of use, it may hurt someone. The ultra-high-power laser pointer has multiple outputs. If the "light intensity" of the high power laser pointer beam is at an illegal level, it can light a cigarette and cut cardboard. It is so powerful that it will be blind at first sight.
