Finding the darkest places in Germany and Central Europe

Andreas Hänel
Dark Sky Germany

Identifying darkest places will be essential to judge if natural darkness can still be found in Germany and establish these as reference locations. This is not easy because it depends on many factors, mainly atmospheric quality. Another factor is that reference values depend on the spectral sensitivity of different sensors that are used for the measurements: luminance meters, SQM, TESS-W, digital cameras. We will discuss these problems and how we identified the darkest places in Germany’s Wadden Sea area.
