Here is a two image mosaic view of Brocchi's Cluster, also known as Collinder 399. It forms an asterism called the Coathanger, can you see it? If you look to the right of my image, you'll also spot the open cluster NGC 6802. The top two stars in the Coathanger are M and K class stars and have a noticeable orangish color to them.
