What you can see from the Birmingham 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 Birmingham itself on a clear, moonless night run to about magnitude 4.0 or brighter, and the Milky Way is not visible. Dixiana is a regional drive away (18 mi) and improves to roughly Bortle 5.

Of the 24 towns rated in this dome, most read Bortle 7 (11 towns) — spread across 5 darkness classes overall. Beyond Birmingham itself, Hoover, Vestavia Hills, Alabaster round out the largest towns sharing this same light dome.
