Planetarium Show at 7:45PM
Telescope Viewing, weather permitting 8:45PM-9:45PM

Our program includes an immersive full dome planetarium show.  The immersive fulldome feature film is followed by a star/constellation show highlighting our current evening sky and where to find the planets in the sky.  Following the planetarium portion of the evening visitors will then have the opportunity to view the MOON (if at the proper phase), JUPITER, SATURN, and other assorted celestial hor d'oeuvres through Indiana's largest telescope, weather permitting. Viewing through the telescope is always free and weather permitting (click on ClearSky Clock below for likely weather conditions).

Admission is $5 for children and students under 18 and $7 for adults for the planetarium show. We accept cash or credit. Tickets can be purchased in the lobby after doors open. 

If a weekend tour doesn’t fit your schedule consider scheduling a group tour for your group at another time. 

Please follow us on Facebook at for up-to-date information and other astronomy information. Holcomb Observatory and Planetarium is located on the north end of the Butler University campus and can be reached by heading west on 46th or 49th Street from Meridian Street. Butler University Campus Map. Patrons can utilize our parking garage for a fee or park in the Hinkle Fieldhouse lot at no charge (provided no sports or special event is scheduled). For patron information there are three separate sets of steps totalling 66 to the telescope. No elevator is available to the telescope viewing area. Wheelchair accessibility is available in the lobby, planetarium, and restroom only. If needed we can bring out a portable telescope for viewing at ground level. If you may need this, please email us in advance.

*Note that we have limited seating capacity so if the 1st planetarium show fills up we run a second and perhaps a third planetarium show that night. If you are in the second (or third) show, then we reverse the order of the evening and get you started on telescope observations of the cosmos immediately. This should result in very little delay in your visit.

**Though you will always see the telescope, its movement, and how it functions, telescope observations are weather dependent.
