At the Landessternwarte a new CCD polarimeter was constructed to observe magnetic fields (Davis-Greenstein) of nearby galaxies. This program is performed in collaboration with the MPI für Radioastronomie Bonn. By means of a focal reducer, the instrument records a field of 14.4 × 9.6 arcminutes at the 1.23-m telescope of the MPI für Astronomie on Calar Alto. Hence galaxies with large angular diameter, which have already been observed with the 100-m radio telescope Effelsberg, can be observed.
