What to Expect
Visitors will enjoy an hour-long tour consisting of a 3D immersive fulldome planetarium program, an interactive seasonal star planetarium show, a tour of the lobby with explanations of the symbols on the terrazo lobby floor and the stair railing, along with a visit to the telescope dome. In the telescope dome the guide will explain and demonstrate the operation of the Holcomb Telescope. If your tour is scheduled after sunset you'll get a chance to look through the telescope if weather conditions permit.
From 2018 to early 2019 the planetarium underwent a $250,000 renovation. It had its old Spitz AP3 star projector replaced with a fulldome Digitarium Kappa projector that projects more that 4 million pixels onto the dome of the planetarium which gives visitors a fully immersive 3D experience in addition to nicely rendering the night sky. Beside the new projector, new comfortable theater seating, a 5.1 surround sound system, new carpet, and cove lighting were added to enhance your experience with the help of our corporate partner Indianapolis-based Bowen Technovation. In addition to the planetarium from 2013 to 2015 our large telescope underwent a $425,000 refurbishment by Astronomical Consultants and Equipment with a grant from the Silicon Valley Community Foundation via Frank Levinson, PhD.
