The guide star was Rasalhague. North is at the Fig. 11. A mosaic of the Milky Way from Deneb in Northern Cygnus to Sirius in Cams Major made to demonstrate that astronomical photography is practicable at sea on a routine basis. This mosaic is composed of 16 exposures, each of 15 min duration, made from R. V. Chain in latitudes 12° to 14° north on the 65° west meridian during the nights of 4th and 5th May, 1962, using a Schneider Xenon lens of 50-mm focal length working at //2 on Tri-X film. The principal objects are from left to right: Deneb, Vega, Altair, Scutum Sobieski, Sagittarius, Scorpio (Antares), a Centauri, the southern coal sack, southern Cross, Argo Navis, Canis Major (Sirius). The Argo region is faint because it remained low on the southern Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hill, M.
