NGC 3581
18" (7/7/02 - Magellan Observatory, Australia): NGC 3581 is the brightest section of this complex and has sharply defined borders running SW-NE and NW-SE, meeting at a right angle about 1' WNW of mag 9.2 SAO 251313. The overall size is ~2'x1.5' with an irregular surface brightness. NGC 3581 is just disconnected from NGC 3582, which is close NE.
A very young, infrared cluster (identified in SIMBAD as " NGC3576 IR Cluster") is on the western side of the HII region, including a number of massive young stellar objects (YSOs).
