We have observed the nucleus of NGC2110 (a Seyfert S0 galaxy with a radio jet) with the Keck OSIRIS instrument (using AO) across the infrared in the J, H and Z bands, with a resolution of 5 pc per pixel. The circumnuclear torus is resolved into a number of luminous star clusters, which are each comparable to the mass and luminosity of the Arches Cluster at the centre of the Milky Way.

The cluster age, star forming rates and interstellar reddening are estimated. An upper limit to the kinematically determined mass of a central supermassive black hole is calculated.
