Ohio under the stars

Main Observatory Building – Cincinnati Observatory Center

This site is a place where visitors may see and learn about the rich astronomical heritage of the state of Ohio. This Great Lakes state is not known for many days of crystalline skies, and yet several outstanding observatories have been built here and equipped with their day’s cutting-edge telescopes. Two of the oldest observatories in the nation still stand in Ohio! Astronomy is not all in the state’s past, however, and our love of the celestial realm is easily seen in the many observatories still in operation and in a growing “dark skies” movement. This site is under active construction so please check back and see what has been added. You may be surprised! — James Guilford

ECLIPSE NOTE: On August 21, 2017 the Continental United States will be graced by a solar eclipse. For information on programs, eclipse glasses, and other eclipse-related questions please use the contact information you will find on the page describing the observatory in which you are interested. Observatories of Ohio seeks to document the state’s facilities but does not operate or speak for any of them.

The path of totality — the area within which a total eclipse of the Sun may be seen — will cross the entire continent, passing south of Ohio. In the Buckeye State, we will see a partial eclipse — only part of the Sun will be covered by the Moon — ranging north to south from about 80 percent to 91 percent covered. At its peak, viewed from Ohio, the Sun will be reduced to a brilliant crescent in our afternoon sky. It is absolutely critical to understand that IT WILL NEVER BE SAFE TO VIEW OUR PARTIAL ECLIPSE WITHOUT EYE PROTECTION!  According to a statement from NASA, “The only safe way to look directly at the uneclipsed or partially eclipsed Sun is through special-purpose solar filters, such as ‘eclipse glasses’ or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the Sun.” Check local museums, science centers, observatories, and astronomy clubs to see if they are offering public programs featuring safe eclipse-watching methods.
