Open Cluster NGC 3532: This Open Custer is for me one of the most magnificent of all the wonderful open clusters in the southern skies. It lies very close to Eta Carinae  and can be recognized with unsupported eyes at a dark night. In a low power telescope or even better with binoculars it is an unforgettable sight with its extended shape, which slightly resembles a fish. Hundreds of differently colored stars never end to amaze one.
