Lists of S, C, MS stars and emission objects revealed in red light observations.
Abstract
Lists are presented for 91 S, C, and MS stars as well as 1174 emission-line objects observed in red light over an 11-year period. Finding charts are also given for 81 of the stars and 602 of the emission-line objects. The latter objects include emission-line galaxies, emission nebulae, planetary nebulae, Wolf-Rayet stars, Bep stars, T Tauri stars, and possible symbiotic stars. Objects exhibiting H-alpha emission are identified along with star clusters and nebulae associated with the emission-line stars, 24 possible T Tauri associations, as well as stellar associations, clusters, and groups associated with the H-alpha stars. Visual estimates of the H-alpha line intensities are provided, and rough estimates of spectral type are made for most of the stars observed.
