Top: dust temperature map of the Sh2-90 complex centered at α₂₀₀₀ = 19^h49^m21^s, δ₂₀₀₀ = + 26°50′18′′. The horizontal color bar is labeled in units of kelvin (K) and the contours are at 14.6 K (yellow), 18 K (red), 19 K (blue) and 23 K (black). The map was obtained by fitting the dust emission between 160 μm and 500 μm. Bottom: H₂ column density map of the same region. The horizontal color bar is labeled in units of cm^-2 and the contours are at 3.3 (yellow), 6.4 (white), 9.3 (black), 12 (cyan), 16 (blue) and 32 (green) × 10²¹ cm^-2. North is up and east is to the left. The labeled axes are in J2000 coordinates. The plus symbols represent the locations of the IR sources shown in Fig. 1.
