This cluster spans about a third of my 50 arcmin field, indicating that visually it is about 17 arcmins across. This is considerably smaller than the catalogue data. The cluster stands out well from the background. It is a dense cloud of medium to faint stars preceding a much brighter (8th mag?) star which is probably unrelated to the cluster. The N edge of the cluster is defined by a line of 8 stars running roughly E-W.  The outline of the rest of the cluster is irregular. In the SW corner there is a ‘hook’ of bright stars. The arrangement of stars suggests several patterns. I fancy I see a perching eagle! In all there are perhaps 40 leading stars of roughly similar magnitude and then many fainter stars, too many to count.
