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.

Surface distribution of the luminous and early-type emission stars in the OB Vulpecula associations
The surface distribution of the luminous and early-type emission starsin a Milky Way region in Vulpecula is obtained. The results show adiscrepancy between the places of greatest concentration of such kindsof stars and those indicated in literature as positions of OBassociations.

UBV photoelectric photometry of early type stars in the direction of the association VUL OB1 and VUL OB4.
