Holcomb Observatory and Planetarium has been serving Butler
University students and the Indianapolis public for 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 2014 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. This telescope gives us great views
of the planets! This Spring our two main targets are Mars and
Jupiter. We are looking forward to having our
greatly improved main 38-inch telescope back online
in late 2014. See the tab to the lower left for more
information about the upgrades.
