Images from 8.8 to 12.5μm of the luminous young stellar objects(YSOs) W3-IRS5 and MonR2-IRS3, and of the Herbig AeBe stars Z CMa and LKHα 101, associated with molecular outflows, are presented. The images were obtained through the mid-IR camera TIRCAM, with a pixel scale of 1.23"/pix, operating at the 1.5m Italian Infrared Telescope (TIRGO). The observed point-spread function has a FWHM size of =~3.0". With deconvolution algorithms a spatial resolution of ~1.8"can be achieved. At these scales, the two Herbig AeBe stars and the luminous YSOs MonR2-IRS3 are unresolved, while W3-IRS5 shows an effective extended emission of elliptical shape, 2.3" wide along its major axis, similar to those seen in other outflow objects, and indicative of the possible presence of disk-like structure around a cluster of embedded B0.5-B0 stars.
