Luxmeters and Luminance meters. Illuminance and luminance can be measured with commercially available instruments, called luxmeters or luminance meters.

Bortle Scale 1: Excellent Dark-Sky Site There is no visible light pollution anywhere—including no light from the Moon—and there are so many stars overhead that you can't easily make out the major constellations. One can easily see the Andromeda Galaxy, the Orion Nebula and many globular clusters with your naked eye.

Dark-sky compliance is defined by the approval of outdoor lighting ordinances through the IDA Fixture Seal of Approval program, which declares: A fixture must be fully shielded and emit no light above the horizontal plane. There shall be no sag or drop lenses, side light panels, uplight panels, etc.

The Bortle scale is a nine-level numeric scale that measures the night sky's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution. John E.

Class 4: Rural/suburban transition Zodiacal light is clearly evident but doesn't even extend halfway to the zenith. The Milky Way well above the horizon is impressive but lacks all but the most obvious structure.

The Bortle Scale rates how well you can see celestial objects in a certain place, taking into account light pollution and sky glow. Lower numbers indicate darker skies. For example, Big Bend Ranch State Park has a Bortle Scale rating of 1, while Cedar Hill State Park, near Dallas, has a Bortle rating of 7.

The most commonly used methods of measuring the light pollution are those using photometers and digital cameras3,15,16,19,20.

Sky brightness refers to the visual perception of the sky and how it scatters and diffuses light. The fact that the sky is not completely dark at night is easily visible. If light sources (e.g. the Moon and light pollution) were removed from the night sky, only direct starlight would be visible.
