A widefield view of the region around the Heart and Soul Nebulae in Cassiopeia, including the Double Cluster over the border in Perseus.

Other objects included in the frame are the reflection nebula LBN 142.14+01.97 to the left of faint emission nebula Sh2-202 (left of the Soul, crossing into Camelopardalis), open cluster Stock 2, and galaxies Maffei 1 and 2 south of the Heart. All these in addition to a host of smaller clusters in the NGC/IC catalogues. North is roughly up from the centre of this image.
