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.
