The Mid Cheshire Astro Soc met last Thursday and had an interesting talk about light pollution from Malc Beesley from Macastro. He's part of the MyDarkSky project, which aims to allow followers to plot their own SQL and NELM measurements on Google Maps, with the hope that it will be a resource for locals and visitors, and also maybe a campaigning tool if a locally dark sky site is threatened. The site is currently offline (it was up for a couple of years, but has been down for the last 12 months), but it is now being re-hosted, and will be available on http://www.mydarksky.com/defaultsitein due course. The maps will look like this, and the hope is for coverage to be national or wider
