Three-colour image of the Coronet cluster (WISE 3.4 µm, blue, 4.6 µm, green, and 12 µm, red, bands; Wright et al. 2010) overlaid with the SCUBA 850 µm density flux from Nutter et al. (2005); contours are in decreasing steps starting at the peak flux (3.7 Jy beam⁻¹) and subtracting 30% from the previous level. The white stars mark the positions of Class 0/I YSOs in the Coronet region (Peterson et al. 2011; Nutter et al. 2005), whereas the orange stars indicate the Herbig Ae/Be star R CrA and the T Tauri star T CrA. The pre-stellar core candidate SMM1A is indicated with an orange circle and the orange square represents the Herbig Haro object HH100.
