The Schmidt-Cassegrain camera system obtained ultraviolet pictures of 36 star fields. A typical observation target, the Pleiades (fig. 2-20), was photographed in a 21-min exposure. It is an example of a group of some 300 young, hot stars (not all seen here) formed about 60 million years ago. The stars are embedded in nebulous matter, which produces the haze seen around the bright stars. This haze is seen in the ground-based,....."
