Title: Multi-colour Photometry of Old Open Clusters

Abstract: We propose to obtain deep UBVRI photometry of the distant old clusters Saurer A, NGC 1193, Berkeley 66 and Berkeley 29 to improve the determinations of their ages, distances and abundances. This is planned as the first of several investigations of old open clusters. Open clusters older than 1 Gyr help in our understanding of the early stages of the formation of the galactic disk, but to this end accurate basic cluster properties are required. Two of our targets are believed to be the most distant open clusters known so far, and their study is valuable to investigate the open-cluster population of the outer galactic disk. The selected objects have not been included in other larger scale projects.
