Scientific paper

A new near-infrared camera, SHARP (System for High Angular Resolution Pictures), has been used at the 3.5m ESO NTI' to produce near-diffraction-limited K-band images of the galactic centre region. The new images show a substantial improvement in resolution and sensitivity over previous K-band images. IRS 16 splits into about 20 compact sources, the extended ridge in IRS 16W- E is resolved into at least 5 stellar components, and a faint source (K = 13.7 ± 0.6) is detected at the position of SgrA. Measurement of proper motions of the stellar sources within a few arcseconds of this source will allow us to determine the central mass within the next few years
