BVRI CCD frames of NGC 604, the brightest Hll region in the nearby spiral galaxy M33, have been obtained at the Nordic Optical Telescope (Canaries Islands). The seeing was 0.6″ which corresponds to ~ 2 pc. at the distance of M33. The magnitude of the stars were obtained using the Capella stellar photometry package (Debray et ai., 1989).
