Catalogue of H-alpha emission stars in the Northern Milky Way
The ``Catalogue of Stars in the Northern Milky Way Having H-alpha inEmission" appears in Abhandlungen aus der Hamburger Sternwarte, Band XIin the year 1997. It contains 4174 stars, range {32degr <= l() II< 214degr , -10degr < b() II < +10degr } having the Hαline in emission. HBH stars and stars of further 99 lists taken from theliterature till the end of 1994 were included in the catalogue. We givethe cross-identification of stars from all lists used. The catalogue isalso available in the Centre de Données, Strasbourg ftp130.79.128.5 or http://cdsweb.u-strasbg.fr and at the HamburgObservatory via internet.

| The Henry Draper Extension Charts: A catalogue of accurate positions, proper motions, magnitudes and spectral types of 86933 stars
The Henry Draper Extension Charts (HDEC), published in the form offinding charts, provide spectral classification for some 87000 starsmostly between 10th and 11th magnitude. This data, being highlyvaluable, as yet was practically unusable for modern computer-basedastronomy. An earlier pilot project (Roeser et al. 1991) demonstrated apossibility to convert this into a star catalogue, using measurements ofcartesian coordinates of stars on the charts and positions of theAstrographic Catalogue (AC) for subsequent identification. We presenthere a final HDEC catalogue comprising accurate positions, propermotions, magnitudes and spectral classes for 86933 stars of the HenryDraper Extension Charts.
| Faint H-alpha emission objects near the equatorial selected areas
An objective-prism survey of fields centered on the 24 Kapteyn SelectedAreas along the celestial equator has resulted in the detection of 120faint H-alpha emission-line objects. Diffuse objects and stars havingmolecular bands in their spectra are not included. Only 18 of thesestars were identified in previous lists of emission-line objects.Identifications were found for an additional three stars. Images ofthese objects appear to be stellar on direct plates. The magnitude rangefor these stars is V = 10.1-19.00. Positions and V magnitudes of theseobjects are provided, as are identifications of objects which have beenreported in other lists. Frequency distributions of the apparentmagnitudes and Galactic latitudes of these emission-line objects arediscussed, and finding charts are provided.
