SH2-284

sh2-284lrgbv4

This is an often overlooked emission nebula near the constellation of Orion. Sh2-284 is a giant HII region. Inside of it is an open star cluster, whose light is energizing the hydrogen gas in the nebula. Stellar winds from the star cluster are clearing out the center of the nebula, giving it a distinctive somewhat hollow spherical shape. This is 8 hours of exposure over several nights of only fair sky conditions ending February 20, 2014. To reduce the noise I will need more exposure.
