Harrington writes that the cluster "looks like a miniature Corona Borealis, with eight 7th mag stars arranged in a semi-circle. Another three dozen fainter stars are scattered throughout the field. Use wide-field binoculars for the best view."

Binoculars shows this cluster which lies in a rich portion of the Milky Way. It is not well separated from the background, and appears essentially as an incomplete circle of five reasonably bright stars. The cluster appears divided into two halves; the south-western section contains three of these stars as well as a sprinkling of a half dozen or so fainter members, whereas the north-eastern part contains the remaining two stars of the circlet, and about a dozen or so fainter stars. An obvious dark band bisects the cluster. Nearby lie NGC 3532 and Cr 240.
