Faint H-alpha Emission Objects Near the Equatorial Selected Areas
Abstract
An objective-prism survey of fields centered on the 24 Kapteyn Selected Areas along the celestial equator has resulted in the detection of 120 faint Hα emission-line objects. Diffuse objects and stars having molecular bands in their spectra are not included. Only 18 of these stars were identified in previous lists of emission-line objects. Identifications were found for an additional three stars. Images of these objects appear to be stellar on direct plates. The magnitude range for these stars is 10.1 < V < 19.0. Positions and V magnitudes of these objects are provided as are identifications of objects which have been reported in other such lists. Frequency distributions of the apparent magnitudes and galactic latitudes of these emission-line objects are discussed and finding charts are provided.
