Left: color-composite image of Sh-90 centered at α₂₀₀₀ = 19^h49^m13^sδ₂₀₀₀ = + 26°49′54′′, showing point sources at 1.25 μm (blue), 2.14 μm (green), and 5.8 μm (red). The names refer to the different IR blobs (see Sect. 6.4) and 250 μm clumps (see Sect. 5.3) identified in the complex. The yellow contours represent the 250 μm clumps. The contours are at 1450, 2000, and 3000 MJy sr^-1. The small circles mark the position of the NIR sources that lie within these IR blobs and clumps. North is up and east is to the left.
