Color composite of the 7′3 × 7′4 deep field observed with the VLT. Blue corresponds to the I band observed with FORS2, and green and red to the J and K_S bands, respectively, observed with HAWK-I. The images used in this composite were obtained by stacking together the observations obtained through each filter on the different nights in which the observations were carried out. Heavy reddening is present only along the south and east edges of the field, covering approximately 30% of the area. The nebular object seen around mid height near the left edge of the field is the Herbig-Haro object HH 78, which has its origin at the embedded Class 0 source Lupus3 MMS (Tachihara et al. 2007).
