The four stars at the center of this image are known as the Trapezium and are not found in most photographs of this nebula because traditional film-based images must overexpose this region in order to show detail in the fainter nebulosity.      

This image was captured on 8 October 1999 and is a composite of numerous 1/2-second exposures through filters in the following amounts: cyan (50x0.5sec), magenta (49x0.5sec), yellow (50x0.5sec) and white (IR filter only 52x0.5sec).
