1 mag 8.0 21.99+ 2 mag 7.5 21.89+ 3 mag 7.0 21.69+ 4 mag 6.5 20.49+ 5 mag 6.0 19.50+ 6 mag 5.5 18.94+ 7 mag 5.0 18.38+ 8 mag 4.5 18.00+ 9 mag 4.0
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.
