DarkZone 2

DarkZone2 allows astronomers and other researchers to read a sky brightness value from an ethernet-connected Sky Quality Meter and show the value in multiple units of measure. It also shows the corresponding dark zone color as defined by the New Atlas of Artificial Sky Brightness (2016, Falchi et al).

Units of measure are:

Mpsas = magnitudes per square arcsecond
Nelm = naked eye limiting magnitude
Mcdpsm = millicandelas per square meter
