Although I used to use a laser pointer at star parties, I have become rather reticent in recent years. They do look rather ‘cool’ at night, so i’m not sure i’d like to encourage those who don’t understand the dangers…
There are already restrictions on use near airfields, and sensible use at star parties will probably not be a problem – but you might end with a visit from the police regardless these days… I am not sure the hassle would be worth it.
