cave nebula final Jpg Low Res 2

Here is my image of the faint Cave nebula, Sh2-155 in the Sharpless catalog. It is located in the constellation Cepheus. (King Cepheus, husband of Cassiopeia and father of Andromeda). This large nebula complex contains regions of diffuse, emission, reflection, and dark nebulae. It is also a region of star formation. The largest contribution of my image is derived from hydrogen alpha emissions, that is, from emanations of light derived from hot ionized hydrogen gas.
