+1 for relying on the SQM, which is 20.9 on a good night at my obs. Bretti reaches 21.7 -21.8. However, the SQM, being so sensitive, can actually produce lower reading because of the overhead Milky Way light pollution. I kid you not, at certain times of the year, SQM readings can be affected by the Milky Way.
