What you can see from the Houston 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 Houston itself on a clear, moonless night run to about magnitude 4.0 or brighter, and the Milky Way is not visible. The Woodlands is a regional drive away (28 mi) and improves to roughly Bortle 6.

Of the 35 towns rated in this dome, most read Bortle 7 (17 towns) — spread across 4 darkness classes overall. Beyond Houston itself, Cypress, Pasadena, Pearland round out the largest towns sharing this same light dome.

The sky from 29.8°N

Never sets: Polaris, the Big Dipper
Never rises: Alpha Centauri, the Southern Cross
Skims the southern horizon: Canopus (peaks 8° up)
Milky Way core: culminates 31.2° above the southern horizon — it rides high in the south in summer, which is about as good as the core gets from the United States.
Longest night: 13 h 55 m at the December solstice, 10 h 05 m in June.
Midsummer: the Sun reaches only 36.8° below the horizon at solar midnight in June — past the 18° astronomical-night mark.
