IC 1871 Nebula in Ha

The Soul Nebula (Sharpless 2-199, LBN 667) is an emission nebula also in Cassiopeia. Several small open clusters are embedded in the nebula: CR 34, 632, and 634 (in the head) and IC1848 (in the body). The object is more commonly called by the cluster designation IC1848. Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area. This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the ''Heart and Soul''
