This is a color composite image made by Karen Gloria at
Hopkins Observatory using a 6-inch refractor and a 512x512
element CCD detector. This is the famous Trifid Nebula,
often photographed. It is a nice illustration of the
combined effections of ionization and scattering caused
by the large yield of blue and UV photons from newly formed
massive stars.
