Reprocessed some data from 2005-12-13 to produce this image. This is a combination of 4s, 8s, 15s, and 60s images. The longer exposures bring out more detail in the faint nebulosity, while the shorter exposures bring out detail in the bright areas such as the trapezium (four closely spaced bright stars near the centre of the nebula).
Images taken 2005-12-13 with ST-2000XCM one-shot colour camera. Reprocessed 2006-06-07.
