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.  Please go to the tours tab to the right for more information.

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.
