NGC 1869-71 Nebulae and Open Clusters in LMC

This photo shows the Super-Bubble DEM L106 or NGC1871 in the LargeMagellanicCloud (LMC).The open clusters NGC1869,1871 and 1873 are the results of intense star formation processes.

Hen S22 is a luminous supergiant,N30B an active Ha-region inside NGC1871

All these open clusters were discovered by James Dunlop in 1826.
