Cassiopeia is one of the 'umistakable' constellations. It is circumpolar from the UK, meaning it is visible all year round as it swings round the Pole Star almost exactly opposite the Plough. There are a host of deep sky objects, mainly open clusters, with many, by their proximity to the main stars of this bright constellation, very easy to find. The Double Cluster (in Perseus) is visible in one of the images. To the left a red mark indicates nebula IC1805. Close to the 'W' lies the cluster and nebula NGC281. Facing the Double Cluster M103 and NGC663 are visible. M52 lies at the top of the images.
