An intuitive system of diagrams for use in this activity was popularized by Donald H. Menzel’s 1975 Field Guide after being proposed in 1952 by H. A. Rey, the creator of Curious George. GoTo mounts used in this activity are software-controlled, unlike traditional clock drives, and can be used with databases like Patrick Moore’s Caldwell catalog. Instruments like Dobsonians may be tuned with collimators and set up in backyards for this activity, whose participants (10[1])may try to find the “pointers” Merak and Dubhe (“DUB-ee”), or Alnitak, Alnilam, and (10[1])Mintaka. People doing this activity often seek out places with low light pollution (10[1])and use (10[1])apps like SkySafari.
