Can you visit Apollo Observatory? Yes
Operated by Miami Valley Astronomical Society atop Boonshoft Museum; club meetings and occasional public observing.
A public night at an observatory usually starts at dusk with a short talk, then a line at the eyepiece of the main telescope for the Moon, a planet or a bright cluster, with volunteers' smaller telescopes set up outside. Dress for the night air even in summer: domes are not heated, so the telescope stays at outside temperature. Many nights sell out or cancel for clouds, so check the observatory's site on the day.

How dark the sky is at Apollo Observatory
Apollo Observatory has no Bortle rating in the list yet. The scale below shows what each class looks like.
Sky brightness and class come from the World Atlas of Artificial Night Sky Brightness (Falchi et al. 2016, CC BY-NC 4.0), with natural skyglow added, at the coordinates below. Research telescopes are often sited on mountains above the haze, so the real sky can be darker than the map suggests.
