Second test on Sky Quality meter
Received two more second generation Sky Quality Meter and test it in IAU#333 in Arizona.I am quite satisfied with the precision.
Testing indoor wall brightness
Sky region 1, 2 mechines reading
Zenith, 2 machines reading
We could only know that it has precision, but not too sure how accurate it is.

What are the differences between 1st and 2nd generations? :o About US$129.
Version 2 is more easy to look at the reading.
