Description:
We study the metal-rich bulge globular cluster Terzan 5 by means of VI
colour-magnitude diagrams, with images obtained under exceptional
seeing conditions (0.34"-0.50"). Differential reddening is important
across the cluster. We derive a reddening of E(B-V)=2.49 and a
distance from the Sun d☉=5.6kpc, closer than previous estimates.
Based on the red giant branch curvature, we derive a metallicity
somewhat higher than that of NGC 6553, probably solar.
