A few weeks ago I observed a very small and bright open cluster on the edge of the Heart Nebula in Cassiopeia, Markarian 6. The cluster looks more like a small asterism than a real open cluster, as you can see on the sketch below. Follow this link to my other website, starobserver.eu, for the complete observing report, finderchart, and a beautiful image of the heart-nebula by Dominique Suys (thanks Dominique for granting me permission to use your image for my report!)
