"Streetlight Hack: A Solution to Urban Light Pollution Threatening Astronomy"

A German startup called StealthTransit has developed a streetlamp technology called DarkSkyProtector that aims to combat light pollution and protect astronomy. The technology consists of a device that makes LED lights flicker at a high frequency, a GPS receiver, and a specially designed shutter on the telescope's camera. By synchronizing the telescope's shutter with the LED lights, the technology can reduce unwanted sky glow in astronomical images by 94%. The system could be used to filter out lights from nearby towns and villages as well as those surrounding the observatory itself. While the technology is not yet ready for commercial use, StealthTransit hopes to have a product available for larger telescopes in five to seven years.
