The College of Southern Idaho's Centennial Observatory

The Centennial Observatory

Centennial Observatory Logo

The observatory features one of the world's largest fully wheelchair-accessible public telescopes.  The main instrument is the Norman Herrett telescope, a 24" Ritchey-Chrétien reflector on a computer-controlled fork mount, manufactured by DFM Engineering of Longmont, Colorado, USA.  An elevator takes visitors to its second-story location at the south end of the museum. Once there, a wheelchair elevator takes visitors with limited mobility to the observing deck under a six-meter (20 foot) motorized dome manufactured by Observa-Dome of Jackson, Mississippi, USA.  The ARE-125, an optical "periscope" designed by DFM, allows unprecedented access to the telescope for wheelchair-bound or limited-mobility visitors.  An Apogee Alta E47+ CCD camera is available for imaging, a generous gift of Dick and Jody Shotwell.
