Notes: This cluster occupies more than half of my 50 arcmin field. The region around the cluster is quite busy with stars so I can’t really appreciate the cluster in its setting. The cluster’s centre is signalled by half a dozen pairs of wide, bright doubles. In all I estimate there are more than 60 stars, all fairly bright. The brain seems to parcel them into small groups making a variety of shapes and patterns. There is no impression of drifts of fainter stars down to the limit of the telescope, as one gets for example with M11. This makes the cluster appear loose and open.
