Description:
In the neighborhood of the famous Coathanger asterism lies this rather small, asymmetrical, faint open cluster. It's very spectacular thanks to its mysterious silver glow. About 8 to 10 cluster members are visible with direct vision, however plenty of stars are on the edge of visibility when looking with averted vision. These and the invisible companions are responsible for the shiny background glow that is elongated in the N-S direction and sometimes looking very elliptical. Despite it being very faint - or perhaps that is the reason - it is a very remarkable cluster.
SQM reading: 21.27 MPSAS, 11°C, humid.
