NGC 1746 is in the Catalog as an open cluster, but it may be just an asterism according to a study by some Spanish Astronomers*. What is interesting is that two clusters (NGC 1750 and NGC 1758) which are background line of sight to NGC 1746 do seem to be open clusters (stars formed from the same molecular cloud).
