"The Sky quality meter (SQM) is very simple to use. Point the lens upwards and press the start button once and release. Under urban skies, a reading will be displayed almost immediatey. Under the very darkest conditions (no moon in the sky, far from civilization) the meter may take up to a minute to complete its measurement. A SQM is an instrument used to measure the luminance of the night sky. It is used, typically by amateur astronomers, to quantify the skyglow aspect of light pollution and uses units of "magnitudes per square arcsecond" favored by astronomers. SQM measurements can be submitted to a database on the manufacturer's website and to the citizen science project GLOBE at Night."--http://www.unihedron.com/projects/sqm-l
