I reported a *21.2* at Farnsworth Ranch. The previous weekend I was on Mount Lemmon, where the SQM gave 20.8 at about the same time of night. The 0.4 magnitudes of additional brightness at Mount Lemmon is compensated by the 7000 feet of additional elevation. Overhead, the Milky Way detail was better at Farnsworth, but as you worked you way to lower altitudes, Mount Lemmon was superior.
