Published in association with the British Astronomical Association's Campaign for Dark Skies, this map is a must for astronomers who want to find the darkest observing sites in the British Isles. Different colours represent different levels of light pollution, and this information has been superimposed over the Philip's road map (scale 20 miles to 1 inch).
