The Centennial 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.

When not open for public viewing, the Norman Herrett Telescope is used to measure asteroids by the stellar occultation method.
