Can you visit Goodsell Observatory? Yes
Free monthly Friday open houses, about 7-9 pm, with historic and modern telescopes; check site for weather cancellations.
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.
