dc.description.abstractWe studied NGC 6522 colour magnitude diagrams using CCD photometry with BV filters. We have carefully estimated the reddening, which is criticai for Baade Window studies, obtaining E(B-V) = 0.55. We derive for this intermediate metallicity cluster, a distance of 6.2 kpc, slightly foreground to the bulk of the metal-rich bulge population. The CMD properties of the cluster core show an enhanced and extended blue horizontal branch, a characteristic in common with many other core collapsed globular clusters.en
