Holcomb Observatory and Planetarium has been serving Butler
University students and the Indianapolis public for nearly 60
years. The observatory, one of the largest public observatories in
the world, houses a 38-inch Cassegrain reflector in addition to a
number of smaller telescopes. It is the ninth largest telescope
East of the Mississippi River. The observatory can be visited
during our regular public tours listed above or groups can schedule
private tours at other times.

During most of 2013 the main telescope will be undergoing a
$325,000 refurbishment. We will still continue to have
telescope viewing and planetarium shows as usual. A
portable computer controlled telescope will be used for viewing the
planets, Moon, and stars. See the tab to the lower left for
more information about the upgrades.
