Abstract: Observations of NGC 7097 show that there is counterrotation in the inner 1.8 kpc (-20 km/s at 0.88 kpc). This is already known for some time. A 3-integral constant M/L model clearly indicates that the observed counterrotation can be caused by counterrotating stars that are distributed over a large part of the galaxy. The dynamical model implies that for NGC 7097 apparent core counterrotation is not necessarily related to a compact group of stars located in the center of the galaxy.
