Query: NTT follow-up observations of star cluster candidates from the FSR
  catalogue   We are conducting a large program to classify newly discovered Milky Way star
cluster candidates from the list of Froebrich, Scholz & Raftery (2007). Here we
present deep NIR follow-up observations from ESO/NTT of 14 star cluster
candidates. We show that the combined analysis of star density maps and
colour-colour/magnitude diagrams derived from deep near-infrared imaging is a
viable tool to reliably classify new stellar clusters. This allowed us to
identify two young clusters with massive stars, three intermediate age open
clusters, and two globular cluster candidates among our targets. The remaining
seven objects are unlikely to be stellar clusters. Among them is the object
FSR1767 which has previously been identified as a globular cluster using 2MASS
data by Bonatto et al. (2007). Our new analysis shows that FSR1767 is not a
star cluster. We also summarise the currently available follow-up analysis of
the FSR candidates and conclude that this catalogue may contain a large number
of new stellar clusters, probably dominated by old open clusters.
