Sky Quality Meter - measuring the brightness of the night sky
Within seconds you can determine the sky brightness with this compact device. No more "faintest star" estimates, no more being influenced by the observer´s shape of the day or eyesight.
A highly sensitive sensor measures the brightness of the night sky in a solid angle of 42° (FWHM) around the central axis; the determined value is displayed directly in magnitudes per arcsecond².

Possible useful applications are e.g. the objective comparison of different observation sites, the evaluation if a certain object can be observed/photographed this night, the documentation of progressing light pollution and many more.

The bandwidth of the sensor is in the visual range. The measurement itself is fully automatic after pressing the button and takes max. 8 seconds; in addition, the current temperature can be displayed to detect slight drifts due to temperature differences in different measurements.

Alternatively, the SQM is also available in the following versions:
SQM-Lwith lens, precisely defined measuring range in a 20° cone.
SQM-LUwith lens and USB connector.
SQM-LE with lens and Ethernet connection
