Figure 4 "D" shows the positions of various doubles and triples that can be seen within the cluster. I have selected the most interesting and obvious ones that can be seen in apertures between 10cm and 50cm. Sixteen pairs (P) and seven triples (T) are given in the 5' area, which range between 11th and 16.5 magnitude.

Note : 4.5" pixels in declination.
