Observing Notes
Harold Corwin
IC 4854 = IC 4855, IC 4857 = IC 4858, and IC 4871 = IC 4872. These three galaxies were all found by Stewart on two overlapping plates, numbers 5556 (a one-hour exposure) and 5656 (3h 15m). In each case, the positions are only 0.1 minute of time or 1 arcmin different, and the descriptions are accordant. And -- most importantly -- there is only one galaxy at each position that Stewart could have picked up (the edgewise companion to IC 4857 is too faint to have registered on these early Harvard plates).
