Second test on Sky Quality meter

BillYeung

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.

How much do them cost?
What are the differences between 1st and 2nd generations?

BillYeung

About US$129.

Version 2 is more easy to look at the reading.
