SQM-LE
An affordable instrument for continuous and networked measurement of effective sky brightness.
The "Sky quality meter - LE" measures the brightness of the sky in magnitudes per square arc second.

Note: The SQM-LE is intended for remote operation via LAN only; it has no display of its own. If PC-independent operation is desired, please select the SQM or SQM-L.

Applications:
Determine how good your observing site really is.
Compare different locations quantitatively.
Document the light pollution in your region.
Adjust planetarium brightness to realistic levels.
Monitor the sky brightness depending on the time of day, from night to night, from year to year.
Determine if it is worthwhile on a particular night to search for faintest objects on a given night.
Compare the effective sky brightnesses with qualitative

measurements, e.g., using the Bortle scale.
Explore how sky brightness relates to the solar cycle and solar activity.
CCD photographers can determine at what sky brightness the ADC level of the sensor is reached.
