The image shows the spiral galaxy NGC 5364 taken with the Omega Prime Camera of the 3,5m telescope at Calar Alto.  The K' filter which is transparent to light at 2,2 microns was used for this exposure.  The field of view is 6.7 x 6.7 arcmins, north is up. Some bright stars were digitally removed from the frame. In the visual band the light of young stars, so called O, B and A stars, is dominating.  Because these stars have much more luminosity with respect to their mass than dwarf stars like our sun, a study of their light distribution may lead to a wrong evaluation of the mass distribution of a galaxy.  A much better estimate of the mass of a galaxy can be found by observing the light of the stars in the near infrared.  There the emission from the cooler, older stars is dominant.  They are the most long lived and abundant type of stars in a galaxy and therefore constitute most of the mass of a galaxy.  Another advantage of observin gin this waveband is that infrared radiation is not absorbed as much by interstellardust. The galaxy was observed in the context of a program with the aim to evaluate the dark matter content in the centers of spiral galaxies (cf. Kranz et al., CA Newsletter, July 2000).
