What you can see from the Orlando 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 Orlando itself on a clear, moonless night run to about magnitude 4.0 or brighter, and the Milky Way is not visible. Deltona is a regional drive away (26 mi) and improves to roughly Bortle 6.
Of the 47 towns rated in this dome, most read Bortle 7 (20 towns) — spread across 4 darkness classes overall. Beyond Orlando itself, Deltona, Alafaya, Kissimmee round out the largest towns sharing this same light dome.
The sky from 28.5°N

- Never sets: Polaris, the Big Dipper
- Never rises: the Southern Cross
- Skims the southern horizon: Canopus (peaks 9° up), Alpha Centauri (peaks 1° up)
- Milky Way core: culminates 32.5° 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 49 m at the December solstice, 10 h 11 m in June.
- Midsummer: the Sun reaches only 38.0° below the horizon at solar midnight in June — past the 18° astronomical-night mark.
