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. Sigma CMa lies in between the latter two.
Omicron-2 then lies directly between Wezen and Sirius,
while Omicron-1 is just to the right (to the west of)
Omicron-2. Tau is the brighter of the two stars just up and to the left
of Wezen. Furud (Zeta) is the bright star far to the right of Wezen. A line from
Wezen to Adhara points downward toward Kappa. Lambda is then up and to the right
of Kappa. Theta is the brighter of the two stars near the upper left corner.
Sirius is at the southern apex of the Winter Triangle. Canis Major lies to the east of Orion, the two here seen in context. The modestly bright star at lower center is Pi Puppis. The fuzzy spot down and a bit to the right of Sirius is the open cluster M 41.
