Situated in the same wide field view as NGC 3372; the eta carina nebula, is the large and very bright open cluster 3532. The cluster is easily visible to the naked eye and makes a spectacular view with binoculars or a wide-field telescope. It is one of the showpieces of the Carina Milky Way. The individual stars are bright and the cluster is situated in a very rich starfield.
There are three smaller open clusters in the field. The largest is the very scattered cluster Basel 17. It is locsted a little to the south-east (lower left) of the bright, white star. Alongside it to the west is the tiny cluster Loden 280. Both of these clusters are almost lost in the background stars. The third cluster is further to the east, surrounded by a small emission nebula. This cluster is Stock 13. The emission nebula does not appear to have a designation. Neither does the large, but faint emission nebula to the south-west of NGC 3532.
