Madison WI dark sky map

Pittsburgh, PA

This is a map of night sky light pollution around Pittsburgh in Western Pennsylvania with road map overlay. Color encodes sky brightness and legend can be found on ClearDarkSky.com (scroll down). Sadly the best sky within one hour drive from Pittsburgh is 'green'. Wagman observatory is the small cross right above the route number 28; Mingo creek observatory is the small cross beneath Pittsburgh. Both are in the 'orange' zone.

The map is created by manually combining the area light pollution map at ClearDarkSky.com with Yahoo! map . The overlay may not be accuracy, but I hope it is useful.
