ON THE COVER:  The Trifid Nebula was discovered by the French astronomer Le Gentil in the 18th century and cataloged M20 by his countryman Charles Messier. As skilled as these celestial explorers were, none could have imagined the beauty of this nebula photographed with modern color film. A portfolio of other deep-sky portraits by Allan Guthmiller and a description of the telescope he built to make them are in this issue.
