What you can see from the Cincinnati core
The sky is bright enough to read by. Only the Moon, the planets, and the few brightest stars and clusters are visible — the constellations lose most of their fainter stars.
At an estimated Bortle 8, the faintest stars visible from Cincinnati itself on a clear, moonless night run to about magnitude 4.1–4.5, and the Milky Way is not visible. Burlington is a short hop away (13 mi) and improves to roughly Bortle 6.
Of the 35 towns rated in this dome, most read Bortle 6 (14 towns) — spread across 3 darkness classes overall. Beyond Cincinnati itself, Hamilton, Middletown, Fairfield round out the largest towns sharing this same light dome.
