dc.descriptionWe describe multi-wavelength (8--20 micron), diffraction-limited, mid-infrared images of the OMC-1 cloud core in Orion, covering an approximately two arcminute area around the Trapezium and BN/KL regions. We have detected mid-infrared emission at the locations of a subset of the previously identified proplyds in the Orion Nebula along with two new infrared sources. The Ney-Allen nebula surrounding the OB star theta 1 Ori d exhibits a ring or toroidal structure at the longest wavelengths. The BN/KL complex appears as an extended, butterfly-shaped structure with significant bipolar symmetry which is bifurcated by a dust lane at the longer wavelengths. The infrared sources IRc3, 4, and 5 give the appearance of a ring-like structure with a possible jet-like protrusion from its center along a line from IRc2. Derived color temperature and dust opacity maps suggest that IRc3, 4, and 5 may not be self-luminous objects.
