We recommend to examine this image in details (clikc on it to see
it in full resolution) — it reveals bright young
stars in the center, which intense radiation pushes the gas outwards.
Interstellar matter then forms trunks and walls, which can be seen as
silhouettes on the bright background. New stars can possibly form
within the chunks of gas.
Martin used his G3-16200 camera on the 30cm, f/3.8
astrograph. Total exposure time needed to capture this image exceeded
18 hours.
