Description:
Sparsely populated, faint open cluster, hardly separates from the surrounding starfield. Fills about one third of the FoV with about 5 brighter stars and many fainter members. Probably the only interesting feature of this cluster is the tiny circle of faint stars to the SSE of the centre of the cluster. But this feature alone makes it worth a visit. :)
