Holcomb Observatory & Planetarium
Holcomb Observatory and Planetarium has been serving Butler University students and the Indianapolis public for over 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 or groups can schedule group tours at other times.
The telescope has recently undergone a $425,000 refurbishment by Astronomical Consultants and Equipment to greatly improve its optics, operation, and research ability. It is now fully operating again and giving us superb views of our Indiana night sky.
Total Lunar Eclipse January 2019
Holcomb Observatory will be highlighting the Total Lunar Eclipse occurring this month with planetarium shows on Friday the 18th, Saturday the 19th, and Sunday the 20th. The planetarium show will explore eclipses of all types, their history, folklore, and how they have helped us understand the cosmos. There will also be telescope viewing each evening. Follow us on Facebook for up-to-date information on the sky, dates, and times.
