We present speckle masking observations of the core of the Seyfert plus circumnuclear starburst hybrid galaxy NGC7469. High-resolution images were obtained in three different wavelength bands. The images show a ring-shaped emission region with a radius of about 1".3 (~ 400 pc at a distance of 65 Mpc) consisting of about a dozen individual cloud-like features. Near the center of the ring we find a bright unresolved source superimposed on an extended and elongated structure extending about ± 0".4 towards the PAs 50deg and 230deg
