Astrophotography: Proceedings of the IAU Workshop, Jena, GDR, April 21–24,1987

For telescopes with large fields of view, in particular Schmidt telescopes, photographic plates are the only suitable radiation receiver. All these topics were discussed in the workshop by the 62 participants (26 from the GDR and 36 from 13 other countries. The treatment of the plates in the photographic laboratory is also very im­ portant. Additional factors affecting the scientific results are the measuring machines and the methods of interpretation. Poster papers are arranged among the other papers according to the topics they treat. Thanks go to David Malin, the chairman of the working group "Astropho­ tography" of the International Astronomical Union, for writing an introduc­ tory article for the proceedings. Thus the effi­ ciency of the photographic plate determines the quality of the observation. I am grateful to all participants who pre­ sented papers during the workshop for sending in their manuscripts on time. The workshop was organized by the Central Institute of Astrophysics of the Academy of Sciences of the German Democratic Republic and is the latest in a series devoted to the problems of photography in astrono
