This general purpose telescope enclosure offers simple access to the sky for small instruments. Its truss roof rolls back on the steel I-beams and tracks that extend to the north of the building. A chain drive attached to the underside of the trusses provides the power that makes opening the observatory simple. Heavy steel pins secure the roof when it is closed. The building is on a concrete pad originally intended for a student radio telescope, and it is serviced by a convenient cable trough that provides power and network from the main building.

The roll roof building houses a Meade 16-inch Schmidt Cassegrain that is used by students and visitors for visual observing and training in CCD use, and it also shelters the Wide Field Spectral Imager research spectrograph.
