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.
