Messier 20


After applying the techniques of unsharp masking and photographic amplifying to this 3-color composite image taken with the 3.9-meter Anglo Australian Telescope, David Malin was able to bring out fine faint details of the Trifid Nebula. In particular, it becomes obvious that the blue reflection nebula completely envelopes the brighter red emission nebula, and itself exhibits a complicated structure. The patchy pattern of dark nebulae is also conspicuous in this image.
