Re: Sky Quality Meter

Tony,

The sensor is on the (front) side with the display (which is off during
measurement, of course!)

You are no doubt aware that there is a trade-off between total signal
and solid angle. Indeed the cone half-angle of 40 degrees will weight
the reading off the zenith, but it is representative of a near-zenith
sky brightness. The actually weighting with altitude would make the
"effective altitude" closer to 60 degrees since the sensor response is
lower at angles farther from the zenith.

Cheers,
Doug Welch
