dc.description.abstract	We have obtained VI photometry for two low Galactic latitude star clusters: BH 176 and AM-2, using the 2.2 m and the 3.5 m 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 dѳ = 13.4 kpc. AM-2 appears to be an intermediate age open cluster, for which a reddening E(B – V) = 0.44 and dѳ = 12.4 kpc are estimated. It is located in the outer regions of the Galactic disk.	en
