IC2162 is a compact diffused nebula lying around the tip of Orion's cudgel. The nebula is positioned at only 2.5 degrees south of "Monkey nebula" belongs to same Orion. Though IC2162 has a smaller size of 15 arc minutes than that of Monkey nebula, fairly photogenic object. But the nebula has fewer characteristics in its shape and has no familiar nicknames like "Monkey nebula", not well known in amateur observers.
Strictly the IC2162 has been registered for only a eastern (left) round nebula, and a center one has a number of Sh2-257, and the largest one in right hand side is Sh2-254.
