Visual Sky Brightness (MPSAS, NELM and Bortle Scale)
A highly digital sensitive sensor measures the brightness of the night sky at a 30° angle. You can determine the sky’s brightness within seconds. The device displays three different scales on-screen (magnitudes per arc second², visual mags, lux). Compare the sky brightness at different sites or documentation of progressive light pollution in your area. Additional calculations
