What you can see from the Los Angeles core
Only the Moon, the bright planets, and a scattering of the very brightest stars pierce the glow. For real stargazing you'll want to drive to a darker site.
At an estimated Bortle 9, the faintest stars visible from Los Angeles itself on a clear, moonless night run to about magnitude 4.0 or brighter, and the Milky Way is not visible. Agoura Hills is a regional drive away (31 mi) and improves to roughly Bortle 4.
Of the 127 towns rated in this dome, most read Bortle 8 (74 towns) — spread across 6 darkness classes overall. Beyond Los Angeles itself, Long Beach, Anaheim, Santa Ana round out the largest towns sharing this same light dome.
