Canis Major (the Larger Dog) is dominated by brilliant Sirius, which lies to the left of upper center. Mirzam is to the right, while much dimmer Mulipein is to the left. The triangle down near the bottom, below Sirius, is composed (clockwise from the lower left) of Aludra, Wezen, and bright Adhara. Omicron-2 lies directly between Wezen and Sirius, while Omicron-1 is to the right (to the west of) Omicron-2. Much fainter EZ CMa is just barely up and to the left of Omicron-1. Sirius is at the southern apex of the Winter Triangle. Canis major lies to the east of Orion, the two here seen in context. M 41 is a fine open cluster. Canis Major has a star with an orbiting planet.
