Prairie Grass Observatory


Prairie Grass Observatory is located under dark rural skies at Camp Cullom (Clinton County Foundation for Youth), between Mulberry and Frankfort, Indiana, and is available to the public.  Technical assistance is provided by the Wabash Valley Astronomical Society in Lafayette.

The observatory has four telescopes: a huge 28″ aperture Dobsonian, a 16″ LX200R Schmidt-Cassegrain telescope, a 16″ Newtonian telescope, and a 7″ apochromatic refractor. The observatory also has a pair of giant 25/40X100 binoculars, and a hydrogen-alpha filter for solar viewing. Click here for more info on these scopes and other equipment at the observatory.
