Can you visit Modine-Benstead Observatory? Yes

Free public open houses on select Friday or Saturday nights (e.g. 7-10 pm), weather permitting.

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.

The Bortle scale. Each panel shows the class number, the faintest star the naked eye reaches at the zenith, and the darkest-edge sky brightness reading of that class in mag/arcsec².

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.
