Scientific paper

We have obtained VI photometry for two low Galactic latitude star clusters: BH 176 and AM-2, using the 2.2m and the 3.5m NTT telescopes at ESO. Their VI colour-magnitude diagrams reveal that: BH 176 may be a globular cluster, or a borderline object between a globular cluster and a disk cluster, showing a red horizontal branch and an extended red giant branch. We estimate E(B-V)=0.77 and dsun_=13.4kpc. AM-2 appears to be an intermediate age open cluster, for which a reddening E(B-V)=0.44 and dsun_=12.4kpc are estimated. It is located in the outer regions of the Galactic disk.
