MALLON PLANETARIUM :The planetarium is named in honor of the founding director; Dr. Gerald Mallon.  At the time of Dr. Mallon's death, he was the president-elect of the International Planetarium Society.  He was awarded the International Planetarium Society Distinguished Service Award.  Dr. Mallon served as our first planetarium director from 1974 through 1991.  Dr. Mallon's work in Participatory Oriented Presentations  and his extensive array of lab experiments to use in the planetarium are in use in many educational planetariums and starlabs across the country.
Our original Planetarium projector was a Spitz 512   originally installed when Arcola opened in 1971.  In 2003 the district installed the Spitz ATM4 to control a full multimedia display including 10 slide projectors, DVD,  MP3 (via PowerPoint) and Video playback.

In 2014 we updated our facility to a fully modern digital planetarium.  Spitz Sci-Dome HD is now the centerpiece of our facility.  Starry Night Software, Layered Earth, and Full dome Spitz player components have been added.  Spitz ATM-4 automation system  was upgraded.  Original slide projectors will be phased out as digital conversion proceeds.  Our existing DVD, Laser Disc and Spitz E-Media capabilities were integrated into our new system.  Below is the new control panel.
