 The planetarium now uses digital hardware and software, greatly increasing its capabilities, and allowing for the projection of specialized 360° video.However, the analog hardware originally used in the 1960s, including a dodecahedron with optical pinholes used for star projection and a control panel, are on permanent display on the main floor of the museum.It is one of only two public planetaria in northern New England, along with the McAuliffe-Shepard Discovery Center.
