open clusters of stars.
Eta Carinae and
HD 93129A, two of the most massive and luminous
stars in our
Milky Way

estimated distance between 6,500 and 10,000
light years from
Earth. It is located in the constellation of

O-type stars. (wikipedia)
I alwayas go to this region to observe a lot of beautiful objects. Here you can see (Down almost in the center) one of my favorite open cluster: NGC 3532, it looks like a lot of shining diamonds. Also you can see, at the right IC 2602, also known as the Theta Carinae Cluster or Southern Pleiades.
