These two very large complexes of faint emission nebulosity are located in Cassiopeia.

Some astrophotographers call these two nebulae the Heart and Soul nebulae, but I call them the Double Nebulae because of their close proximity to the Double Cluster in Perseus, which is located just five degrees away.

IC 1805, the Heart Nebula, is the large area of nebulosity on the left side of the image.

NGC 896, a bright knot of nebulosity, is at the lower left of the photo. The loose open cluster Melotte 15 lies at the center of IC 1805, and open cluster NGC 1027 is just below the center of the image.

LBN 667, the Soul Nebula, is the large area of nebulosity at upper right in the image. Open clusters IC 1848 and CR 33 are embedded in the nebula.

North is to the top in the above image.
