The Bortle scale. Each panel shows the class number, the faintest star the naked eye reaches at the zenith, and the darkest-edge sky brightness reading of that class in mag/arcsec².

Sky brightness and class come from the World Atlas of Artificial Night Sky Brightness (Falchi et al. 2016, CC BY-NC 4.0), with natural skyglow added, at the coordinates below. Research telescopes are often sited on mountains above the haze, so the real sky can be darker than the map suggests.
