The False Cross is an asterism made up of stars from the constellations of Vela and Carina. It is located in a rich region of the Milky Way, a little to the west of the Southern Cross. It is somewhat larger than its more famous namesake, and its stars are all 2nd magnitude so they are a little fainter than most of the Southern Cross.
Being located in the Milky Way, the region abounds with interesting deep-sky objects, particularly double stars and open clusters. In the image below, the cluster towards the bottom right is the beautiful NGC 2516, while the one to the upper right is IC 2391.
