The loose open star cluster IC 2391, aka the Omicron Velorum Cluster in Vela. The orientation is along the Milky Way here, so north is at right, not at top. This is a stack of five 2-minute exposures with the Canon L-series 135mm lens at f/2.8 and Canon 7D at ISO 1250. The field simulates a binocular field of roughly 7°.
