Images of the central region of clump/cluster C1, where a pair of bright stars (A and B) had been detected in previous studies. The left and right panels refer, respectively, to K_s and H band images, while the upper and lower panels show, respectively, images obtained with the LUCI and PISCES+AO cameras. The values of the contour levels are indicated by marks in the corresponding colour scales. Note how employing AO allows us to resolve star A into the two sources A1 and A2.
