I've been searching for a while, but all I seem to find is information about how it's illegal to sell laser pointers to minors in New York City. That and I find some information on what else is illegal to do with a laser pointer in NYC (pointing at vehicles, officers, etc.). There's a lot of air traffic where I live. At least one plane can be seen in the sky at almost any given time. So of course using a green laser pointer for astronomy purposes would need to be done carefully here. However, I can't seem to find information straight out saying whether astronomy laser pointers are illegal or legal. Can anyone shed some light on this matter? Thanks!
