Uses: (http://www.unihedron.com/projects/sqm-lu/) •Find out how good the night or site REALLY is. •Compare the sky brightness at different sites quantitatively. •Document the evolution of light pollution in your area. •Set planetarium dome illumination to mimic the skies people are likely to experience elsewhere in the city. •Monitor sky brightness through the night, night-to-night, and year-to-year. •Determine which nights show the greatest promise for finding the 'faintest fuzzies'! •Calibrate the effect of sky brightness on qualitative measures such as the Bortle Scale. •Investigate how sky brightness correlates with the solar cycle and month-to-month sunspot activity. •Help provide local ground truth for future sky brightness prediction with the Clear Sky Clock. •CCD users can make a correlation between the SQM reading and when the background reaches some ADC level.
