Finding dark skies can seem challenging at first - especially if you don't use any tools to guide you along the way. Sure, you can drive away from the city into the countryside, but there's a little more to it than that. Fortunately, astronomers have been thinking about dark skies for a long time so this isn't anything new.
So over the years, I've come across a few tools that help to identify some locations that would be good and others that don't quite fit the bill. This approach to driving my night adventures with light pollution data is a key part of my dark sky photography planning.
Option #1 - Dark Sky Finder
My favorite tool is called the Dark Sky Finder at http://www.jshine.net/astronomy/dark_sky/ - a website that lays light pollution data over top of a Google Map. This makes it really easy to see just where the light pollution is with colors indicating the intensity of the light pollution - a great asset for planning night photography adventures in the Continental US...
