The region of south central Monoceros, just north of Sirius in Canis Major, is chock full of open clusters and also includes the large emission nebula called the Seagull Nebula based on its shape.  The official designation of this object is IC 2177.  This image faintly records the outlines of the Seagull but we capture all of the open clusters here with relative ease.  Unannotated image.
