Title

SH2-284 Emission Nebula

About this image

SH2-284 is an HII star forming region of dust and gases, sculpted by the radiation and interstellar winds emanating from the young (3 – 4 million years) open star cluster Dolidze 35 located near its centre.  The inner edge of the main ring structure are numerous dark dust pillars and Bok Globules, not unlike those of the Elephant’s Trunk nebula. .            

Despite its close resemblance to the Elephant’s Trunk, the emission nebula SH2-284 seems by comparison somewhat overlooked.  Being some much further away it’s apparent size is good deal smaller and much fainter in nature but still forms an excellent late winter image target.
