    Here is a view of the famous double cluster in the constellation Perseus (between Perseus and Cassiopeia), they are also designate NGC 869 and NGC 884. Check out the red supergiants in this view! Did you know that the Perseus Double Cluster is surrounded by one of the largest concentrations of red supergiants stars in the sky? (Red supergiants, neutrinos and the Double Cluster, Tristram Brelstafff, 1996). Also in this image is a visitor, Comet PanSTARRS (C/2017 T2), you can find it just right of center as a greenish blur with a little tail pointing to the upper left.
