An ethernet-enabled SQM model for night-time sky brightness monitoring! An affordable meter for continual, connected measuring of sky brightness for astronomers! The "Sky Quality Meter - LE" measures the brightness of the night sky in magnitudes per square arcsecond. Designed by Dr. Doug Welch and Anthony Tekatch 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
-

Specifications: Ethernet connectivity Included applications for reading data in Java, C, Perl, Python. The Half Width Half Maximum (HWHM) of the angular sensitivity is ~10°. The Full Width Half Maximum (FWHM) is then ~20°. The sensitivity to a point source ~19° off-axis is a factor of 10 lower than on-axis. A point source ~20° and ~40° off-axis would register 3.0 and 5.0 magnitudes fainter, respectively. Annotated FOV spec. Comparison chart.
