This nebula is located just a few degrees from the Heart Nebula (see previous image) in Cassiopeia. It is composed of two expanding rings of nebulosity, each driven by a cluster of young, hot stars in its interior. The star cluster in the right lobe is IC 1848, and the patch of nebulosity in the bottom right of the picture is Sharpless 198. This image is the result of 7 hours of total exposure (H:O:S = 3:2:2 hours).
