Abstract
In this paper we present preliminary results from the measurement and analysis of images of the ecliptic zone obtained with MegaCam at Canada-France-Hawaii Telescope (CFHT) located at Mauna Kea (Hawaii). We are evaluating the feasibility of constructing an astrometric and photometric catalogue with all the astronomical sources identified on those images. We comment and discuss the criteria and procedures for the identification of sources, the photometric reduction and their classification as stellar or extended objects.
