All about the use
and missuses of Laser PointersLaser Pointers
The Green Laser Pointer is a very useful instrument in the hands of astronomers to point out objects in the night sky for others to see. We have also seen more creative uses, like using it in place of a finder scope. However the missuses of these devices is causing concern and may have some implications for amateur astronomy.
When using these devices be very careful to use them
correctly. Never point them at any one or even at ground level in
case you catch some one in the eyes. Also if aircraft are in the
area, refrain from using until they are gone. If a pilot sees one
of these they may become worried about it hitting them and causing
momentary blindness.
The perception of danger from green laser pointers is out there and it alone may cause these devices to be outlawed. We don't want to see a case where an amateur astronomer is at fault for some damage due to the use of a green laser pointer.
