One of the biggest obstacles of taking good astronomical photos is light pollution, this is why almost every tip article on night photos has a tip about getting away from the city. But what if you want to take photos in your driveway? In that case, street lights will most probably kill each and every one of your photos.
Astronaut Don Pettit (previously) has a neat little trick he uses to shut down that annoying street light he has just outside his driveway. He points a laser at the street light sensor which tricks the street light into thinking that it is still day outside and preserve energy by shutting down.
