We present a catalog of 4780 extended sources from the outer field of M33.The catalog includes 73 previously identified clusters or planetary nebulae,1153 likely background galaxies, and 3554 new candidate stellar clusters. Thesurvey is based on deep ground-based images obtained with the MegaCaminstrument on the CFHT telescope. We provide g'r'i' photometry for detectedobjects as well as estimates of the FWHM and ellipticity of their profiles. Thesample includes 122 new, relatively bright, likely globular clusters. Follow-upobservations of fainter candidates from our list may extend the faint-end ofthe observed luminosity function of globular clusters in M33 by up to 3magnitudes. The catalog includes several cluster candidates located in theoutskirts of the galaxy. These objects are promising targets for deepphotometry with the HST. We present a color-magnitude diagram for one detectedobject, showing that it is an extended and low-surface-brightness old clusterlocated at an angular distance of 27' from the center of M33.
