Stargazing in San Diego, US
San Diego's Bortle 7–8 coastal glow gives way to excellent dark skies in the mountains and deserts to the east. Mount Laguna and the Anza-Borrego Desert State Park reach Bortle 3–2 within 60–90 minutes, and the historic Palomar Observatory sits in the hills to the north. Southern California's famously dry, stable air gives outstanding transparency and seeing for much of the year, and the coastal marine layer that brings morning cloud usually clears the inland observing sites. At 32.7°N, the southern sky is well presented.
