You are exactly right, Gary. Most of the dazzling color photos NASA has released since Hubble went into orbit have been color adjusted to emphasize details in the field. Also, they often combine data from various telescopes (IR, visible, UV and X-Ray) to show a composite image in greater detail than would be possible in a single spectrum. One big advantage of using IR light is the fact that the universe is expanding causing the red shift of light in distant objects. Infrared reveals details that visible light would not pick up.
