Description

Unihedron Sky Quality Meter - LU-DL-V 

A USB enabled vector 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 "Sky Quality Meter - LU-DL-V" (SQM-LU-DL-V) measures the brightness of the night sky in magnitudes per square arcsecond.

Designed by Dr. Doug Welch and Anthony Tekatch
Uses:
  • Measuring the night sky brightness during remote biological field experiments.
  • 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.
