The Trifid Nebula (M 20) is a combination emission and reflection nebula located about 5,200 light years distant in the constellation Sagittarius The Archer. I purposely bumped up the color and tint so you can see the differentiation between ionized gas emissions and mirror like reflections. For example: look at the dark lanes in the red emission nebula on the left and compare it to the very dim blue-violet reflection of that same emission pattern on the dust to the right. The large green star is in the center of the reflection dust nebula. This reflection is a blue mirror image of the bright red emission nebula.

This image was taken in Blue, Visual (green), Red, Infrared, and Hydrogen Alpha light from Mount Sangre Observatory on the night of August 11.
