The onset of massive star formation and the initial conditions of the molecular cores forming massive stars are unclear. The quest is on for High-Mass Protostellar Objects (HMPOs) and the earlier High-Mass Starless Cores (HMSCs). HMPOs would be embedded in a forming cluster, a protocluster, as massive stars only form in clusters. We observed protocluster candidates with the MIPS instrument to constrain their spectral energy distribution (SED) in the far infrared (FIR). The resolution Spitzer provides is crucial to disentangle the contributions of different clumps which were resolved at other wavelengths, but not in the FIR. We will show how the Spitzer observations allowed us to improve previous luminosity estimates by e.g. finding evidence for outside heating or just resolving the FIR emission.
