Stop by about an hour after sunset to view the heavens through the 16-inch cassegrain telescope. An expert astronomer/telescope operator is always on hand to direct your attention to planets, galaxies, star clusters or to answer any questions you may have. The observatory is equipped with a real-time Hyperstar imaging system on an auxiliary telescope, which is able to reveal the tails of comets that can be hard to spot in most city locations. In addition to the observatory, Flandrau also has science exhibits, a planetarium, regular laser shows, and special events. Children under the age of three are not permitted in the planetarium. Reservations are required for observatory (nighttime) viewing. Please note that admission to Science Center Exhibits, UA Mineral Museum and observatory laser shows require paid admission.
