We present the results from the analysis of the machine-readable version of the log book for the 50/70 cm Schmidt telescope of the National Astronomical Observatory (NAO) Rozhen of the Bulgarian Academy of Sciences. The telescope began operating in 1979, after it was repaired and transferred from the Potsdam Observatory where it had operated since 1952.

During our programme for nonstable and flare star investigations in the star forming regions, more than 290 UBVR photographic plates in the field of the bright nebula NGC 7129 were obtained. The photographic observations were made with the 50/70/172 cm Schmidt telescope of the Rozhen Astronomical Observatory of the Bulgarian Academy of Sciences during the period September 1984–July 1993.

Mutual Agreement

The 50/70 Schmidt telescope at the National Astronomical Observatory (NAO), Bulgarian Academy of Sciences, is an example of the possibilities for a long-term operation and everlasting actuality of these types of telescopes. Originally, this telescope was constructed in the GDR in 1952 and mounted in the Potsdam Observatory, Academy of Sciences of the GDR (as such, it is on the list of West, 1974). In 1979, on the basis of a mutual agreement between the Bulgarian Academy of Sciences and the Academy of Sciences of the GDR, it was transferred to Rozhen, Bulgaria. The principal parameters of the instrument are as follows: I. Main mirror: diameter: 70cm; material: Tempax; thickness in the centre: 10 cm; radius of curvature: 344 cm.

The Seyfert 1.5 galaxy Akn564 [1] is a well known X-ray active galactic nucleus (AGN) included in our list of selected barred AGN. The galaxy was observed during the August 1996 season at the 2-m RCC telescope of the Astronomical Observatory “Rozhen” of the Bulgarian Academy of Sciences. ST-6 with standard Schott V, R, I filters were used. MIDAS'96 package was used for the data reduction with teh Richter's expansion for the surface photometry [2]. Most of the basic data for the galaxy are shown in the Table 1 below.

The article deals with the origin of the Bulgarian vocabulary according to the multi-volume Bulgarian etymological dictionary, one of the main nationally significant projects of the Institute for Bulgarian Language at the Bulgarian Academy of Sciences. In summary, it presents the different chronological and genetic layers of vocabulary that build the Bulgarian language. The two main layers of vocabulary are emphasized - the original Slavic and the later Balkan layer, which characterize the language as both Slavic and Balkan. The classical (literary) Old Church Slavonic source is pointed out, as well as other older and new foreign sources and the different ways of penetration of the lexical units into the literary and colloquial language and in the Bulgarian dialects are revealed.

The Relationship

About Ivan Vazov everything seems to have been researched, written and published. Among the many literary criticisms devoted to his life and work, as well as documentary publications, the relationships with his translators and foreign publishers, to whom I believe we have a cultural and moral duty, are very rarely mentioned. However, the correspondence between him and the Croat Fran Gundrum-Oriovac stands out among all. No one else has translated as many of Vazov's works as this Croatian writer. Unfortunately, the acquaintance with Fran Gundrum's archive is indirect, but I would venture to focus on his translation practice, the regulation of relations between the two, their long-term cooperation and the reception of Vazov's work in Croatia. The proposed interpretation of the “File” does not claim to exhaust the relationship between the two. Our task is based on the personal correspondence published in Volume 10 of the Bulletin of the Institute of Literature of the Bulgarian Academy of Sciences in 1961 between Dr. Fran Gundrum and Ivan Vazov – to try to reconstruct the translation and publishing strategies of Fran Gundrum.
