NGC 3766 is between Eta Carina and Crux. It is obvious
in the 10X50s and has a high surface brightness. Only 3 stars
can be resolved with the binocs, but there are many other
bright stars just to the north of this compact cluster.
The 16X80 binoculars resolved 8 members and really frame up
the cluster with the bright stars to the north.
