Measures the brightness of the night sky in magnitudes per square arcsecond
An affordable meter for measuring sky brightness for astronomers! The "Sky Quality Meter-L" measures the brightness of the night sky in magnitudes per square arcsecond with unprecedented sensitivity in a handheld meter!
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.
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.
CCD users can make a correlation between the SQM reading and when the background reaches some ADC level.
Features
Audible signal while measurement is in progress.
Sky brightness displayed in visual magnitudes per square arcsecond.
Infrared blocking filter restricts measurement to visual bandpass.
Temperature in both Celsius and Fahrenheit as well as model number and serial number can be displayed with different button press sequence.
Precision readings at even the darkest sites.
Power-saving features designed in for maximum battery life.
Reverse battery protection.
The Half Width Half Maximum (HWHM) of the angular sensitivity is ~10°.- The sensitivity to a point source ~19° off-axis is a factor of 10 lower than on-axis.
Maximum light sampling time: 80 seconds.
