Description

Ethernet Sky Quality Meter with Lens (SQM-LE)

Een ethernet-enabled SQM-model voor het bewaken van de nachtelijke hemelhelderheid! Een betaalbare meter voor continue, geconnecteerde meting van de hemelhelderheid voor astronomen! De “Sky Quality Meter – LE” meet de helderheid van de nachtelijke hemel in magnitudes per vierkante boogseconde

Uses:

  • 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.

Features:

  • Sky brightness reported in visual magnitudes per square arcsecond.
  • Infrared blocking filter restricts measurement to visual bandpass.
  • Sensor temperature, model number, and serial number are provided.
  • Precision readings at even the darkest sites.
  • Field-upgradeable firmware
  • Open protocol document

Specificaties van de Ethernet Sky Quality Meter with Lens (SQM-LE) zijn:

  • Ethernet connectivity
  • Included applications for reading data in Java, C, Perl, Python.
