measured the sky

Spotted stars as I set up the camera... The CSC had been right.

Took readings from the Bradford backyard with a loaner Sky Quality Meter. Rhonda recorded the values for me.

The first (throw-away) reading was 18.67. I wondered if the deck lights were interfering. We unplugged them. I moved west to avoid the hallway light.

19.29
19.26
19.22
19.25

Temp. showed as 20°C.

Those look like good numbers to me.
