NGC2354 is a medium sized open cluster at the southern Canis Major, about 1.5 degrees east of delta CMa. The cluster has an apparent diameter of 20 arc minutes and a magnitude of 6.5, and it can be easily found by using a noticeable triangle that forms the hind leg of Great Dog as a guide.
You can appreciate another small open cluster of NGC2362 only 1.3 degree ENE from NGC2354. This minor one has a size of only 8 arc minutes, so it should be fairly difficult to distinguish the cluster from the normal stars through binoculars. This image has captured the cluster at the upper left-hand side, it's over exposured around nuclei because of its high-dense stellar distribution.
