Color composite image of the large (2.7° × 2.7°) area containing the Carina nebula and centered at α(J2000) = 10^h41^m175 and . This RGB image was made using the WISE 4.6 μm (red), 2MASS K_s band (green), and DSS R band (blue) images. Approximate locations of different star clusters (Tr 14, 15, 16; Bo 9, 10; Cr 228, 232, and NGC 3324) are denoted by white boxes. η Carinae is marked by an arrow and in the lower left part of the image, south pillars (Smith et al. 2000) are shown. The region covered in the present study is shown by the green box. Part of the selected field region can be seen in the extreme western part of the image. North is up and east is to the left.
