The blue line will decrease as the moon rises, because as the moon climbs higher in the sky, the sky brightens. The finding shows that the darkest the sky can go is to less than 20 mag per meter square in the morning (Subh) while in the night the sky can goes dark until less than 21mag per meter square. Compare the sky brightness at different sites quantitatively. A USB enabled data-logging light meter for night-time sky brightness monitoring! An affordable meter for continual, connected or autonomous data-logging to measure sky brightness for astronomers and light pollution investigators. The Computerized Sky Quality Meter System Controller Pro (Model: SQM-RC-PRO) is a economical yet superior Automation solution made available to the amateur or professional Astronomer. Until Unihedron introduced the Sky Quality Meter (see the box on page 104), no standard commercial light meter was sensitive enough to measure the brightness of the night sky. Cu Sky Quality Meter puteți determina în doar câteva secunde foarte obiectiv luminozitatea cerul.
