Eastern's Main Campus
Julia Fowler Planetarium
Julia Fowler Planetarium was named the "Best Place to Ponder the Heavens" by Main Line Today Magazine (July 2009).Â Throughout the year the Planetarium serves thousands of Pre-K through college students. The planetarium is open to the public three times a year for special presentations including the perennial favorite The Star of Bethlehem show in December. Original Fulldome Curriculum is being developed by Dr. David H. Bradstreet for Spitz, Inc., which will be used worldwide at other SciDome planetariums.Â Read More on Julia Fowler Planetarium.
The Bradstreet Observatory
The Bradstreet Observatory consists of twin 14.5-foot diameter galvaluminum Ash Domes, able to rotate 360 degrees.Â The shutters are designed to slide up behind the dome, with a lower shutter that lowers downward, allowing the observer to see from the horizon to the zenith. The domes are controllable not only from within the dome but also remotely from the Russell Control Room.
The azimuth of the open shutter is automatically read out via digital sensors donated by Ken Goff of Performance Controls, also a member of the Universityâ€™s Board of Trustees. This allows observers in the Control Room to align the dome to wherever the telescope is pointing without having to see either the telescope or the dome. This is critical because most of the serious observing and research is undertaken from the Control Room, not in the domes.
The domes house 16â€ť diameter Meade LX200 Schmidt-Cassegrain telescopes. These telescopes are fully computerized, allowing the user to automatically find 64,000 objects pre-stored in the telescopesâ€™ computer.
The telescopes can also be completely controlled remotely via ancillary computer systems.Â Pentium IV 2.8GHz computers using Software Bisqueâ€™s The Sky6 software allow the user to point and click on a star map and send the telescope precisely to over 19 million objects, the same database used by the Hubble Space Telescope.Â Recent US Naval Observatory software updates have expanded this database to over 526 million objects!Â Read More on the History of the Bradstreet Observatory.
