    The Heart Nebula (IC 1805) lies about 7,500 light years away from Earth in the Perseus Arm of the Galaxy in the constellation Cassiopeia. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. (ref: https://en.wikipedia.org/wiki/Heart_Nebula)

    The Heart Nebula is located adjacent to the Soul Nebula forming a view referred to as the Heart and Soul Nebula. Now to splice the images together into a mosaic of the region.

    Thanks, appreciate it! My work has been published in the past, not this image though.
