See the annotated copy below, to get an insight of the multiple objects present in the image.

NGC 1727 is the reddish nebula that embeds an open cluster located at the center of this image. Actually, this image contains several open clusters (NGC 1712, 1722 and 1727) that were studied in 1990 by M. Kubiak. All these clusters, together with NGC 1711 (just a few arc minutes outside this frame to the right), are very young and were formed in about the same time. All these nebulae are located in the Large Magellanic Cloud, on the opposite side of the Tarantula Nebula (see wide field of the LMC, this frame would be located in its lower right border).
