New Members of the Association VI Cygni.
Abstract
Further observations of the heavily obscured 0-association VI Cygni have been made with the 82- inch McDonald Observatory reflector; photoelectric and spectroscopic results confirm the previous suspicion that a number of fainter stars are early-type members of this association Some rather long- exposure plates of the region are here presented, showing stars of fainter limiting magnitudes; these plates were taken by the use of low-dispersion, slitless-spectrograph techniques and show the same effect of interstellar reddening as was seen with low-dispersion, objective-prism plates
