The new astronomical station at the mountain Vidojevica (ASV) nearby the town of Prokuplje will be finished till the end of 2007. A part of the research at the ASV will be dedicated to the stellar spectroscopy. The Astronomical Observatory in Belgrade provided a spectrograph for this purpose. In the town of Belogradchik in Bulgaria, nearby the Bulgarian‐Serbian border, a small astronomical observatory of the size as ASV is situated and equipped similarly as ASV The aim of this paper is to compare the equipment of these observatories and discuss possible cooperation between them, in particular in those areas of astronomy in which the stellar spectroscopy plays an important role.
