The results of UBV photoelectric photometry with different aperture sizes of the galaxies NGC 205 and M33 are presented, including those obtained with small aperture sizes. With the aperture decreasing, colour of NGC 205 changes first to blue and than to red; it is connected with the existence of a group of young stars in the central region of this galaxy. Colour of M33, with approaching the centre, becomes a little bit redder. Properties of stellar-like nuclei of M31, M32, NGC 205 and M33 are considered. Magnitudes and colours of the nuclei are shown to be different.
