a) A C-band image of the W51e20/e21/e22 cluster. b) An unsharp-masked version of the image with a 0.3′′smoothing kernel. Sources e20, e21, and e22 correspond to two detected infrared K-band sources from Goldader & Wynn-Williams (1994, Table 8 and have K-band luminosities consistent with spectral type O4V or earlier. The other point sources seen in this field are not detected in the near infrared.
