laser use in astronomy? The NANNY-STATE has you covered!!

Lasers and astronomy

Lasers are often used in astronomy to point at stars or sky features. If you plan on aiming a laser into the sky, please complete a notice of proposal form. You can also speak with your local astronomy club – they may have additional information for you.

According to Transport Canada regulations, any person planning to project a laser into navigable airspace must get permission from the department. We give written permission if your laser use is not likely to:

create a hazard to aviation safety
cause damage to an aircraft
cause injury to persons on board the aircraft

We may specify conditions necessary to ensure the safe use of the laser.

The Royal Astronomical Society of Canada has produced a webpage with information and recommendations on green laser pointer usage.
