Astronomy Thursdays, Fridays, and Saturdays


The Cincinnati Observatory is open to the public on most Thursday and Friday nights and some Saturday nights throughout the year. 

Each event includes a 30-minute presentation by a local astronomer on one of the many fascinating topics in astronomy followed by a guided stargaze through the oldest telescope in the United States – a 16-foot long wood and brass refractor first used in 1845 (weather permitting).  We observe a variety of objects including the Moon, planets, and stars. 

If cloudy, you'll be escorted on a historical tour of the observatory where you’ll see not only how the old telescope works but also the “new” one – a 22-foot long metal refractor made in 1904.  You'll also learn about the role that Cincinnati has played in the growth of astronomy in the United States.

  • Astronomy Thursdays admission is by suggested donation of $5 per person.
  • Astronomy Fridays and Saturdays are $7 for adults, $5 for children under 18.
  • Reservations are required for all evenings.
  • Astronomy evenings often book up one week in advance, so register early.

Register online or call 513-321-5186 for start times and reservations.

Programs are held rain or shine. You never know about the weather in Cincinnati and it does not have to be a completely clear night to permit viewing.  If the weather does not allow viewing, the presenters will offer an extended questions & answers session, tours of the two wonderful observatory buildings and show off our two magnificent telescopes. All will just whet your appetite for a return visit!
