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.
