The Trifid Nebula takes its
name from the three dark lanes dividing the red emission nebula. It is located 5,200
light-years from the solar system. As with many other emission nebulae, M20 is
associated with a star cluster still in the process of formation.

Technical Notes: Individual exposures were obtained using CCDAutoPilot2 and then sigma combined. The RGB image was created in
Registar 1.0. Gaussian Blur of 1 pixel was applied to the RGB image and a High Pass Filter
of 4 pixels was selectively applied to the luminance image using a Layer Mask. A duplicate
of the RGB image was combined using Soft Light to increase color saturation.
