Composite color image of the same field shown in Fig. 4, where blue is associated with the GLIMPSE/Spitzer 3.6 μm image, green with the GLIMPSE/Spitzer 8.0 μm image, and red with our 24.5 μm Subaru image. The reddest and hence most extincted source is the one to the north, coinciding with the HMC. The VLA 3.6 cm continuum (from S2010) is shown with white contours. The white dots have the same meaning as in Fig. 4.
