Mika McKinnon from space.io9 explains how you can get back Dark Skies:

“I live in a city. I can see pinpricks of bright stars, but I miss the spill of the Milky Way. Cities don’t need to be this bright, and dark skies don’t need to be a distant memory from trips to deserts, mountain tops, and vacations far from home.”
