With the passing of southern Arizona's steady summer rains, Dave Harvey resumes his ritual for clear desert nights. He crosses his backyard to an 8 x 8-foot wooden shed, surrounded by prickly pear cactus and palo verde, and slides off its peaked roof. Inside resides a 14-inch Celestron telescope attached to a motorized, industrial-strength mount. He starts to cool the compact charged-coupled device (CCD) camera attached to the eyepiece down from ambient temperature. Then Harvey returns to an office in his house where he can guide the telescope and keep tabs on its celestial sightings from a pair of personal computers.
