This is IC 1805 (Sh2-190), the Heart Nebula in Cassiopeia. This rich but faint nebular complex resides 5° NNE of the Double Cluster in Perseus. The largest and very diffuse part of it, IC 1805, contains large and bright star cluster Melotte 15 at its center. Other star clusters (NGC 1027, Berkeley 65 and Markarian 6) are located around its edges. The brightest part of IC 1805 complex consists of nebulae IC 1795 and NGC 896 which together are intersected by narrow NW to SE streaks of dust.
