SkippySky showed the whole of SA to be clear so probably the SQM (Unihedron SQM-LE) was looking at that! Is there a calibration routine I should have run? I read through the Help file but may have missed something.

Charles, the darkest you could possibly get (other down a mine with the lights off) would be a new moon night, far from town, under total cloud. The limit for SQMs is supposed to be about 22. I get high 21s at Willow Tree pointed NE away from the Milky Way.
I know you said you have an SQM-LE, but getting more than 22 with an SQM-L means you should try again with a new battery.
