Top left panel: FLITECAM 3.3 μm PAH filter observation of NGC 7023 with a Δλ = 0.09 μm. Top right panel: IRAC 8.0 μm filter with a Δλ = 2.90 μm. The NW and the S indicate the NW PDR and the S PDR. Bottom left panel: FORCAST 11.1 μm SWC filter observation with a Δλ = 0.95 μm. The bottom right panel is an RGB image of the three images with (in red) the FORCAST, the IRAC (in green), and the FLITECAM image (in blue). All images are normalized to the maximum value in the north PDR. The white box is the region used in the crosscut (see Fig. 6).
