SKY QUALITY METER WITH ETHERNET CONNECTIVITY

Sky Quality Meter with Lens and Ethernet Connection

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.
