William Herschel was the first astronomer to push his investigation beyond the Solar System and to expressly concern himself with the stars and nebulae—the “construction of the heavens.” We now know that it was actually his sister, Caroline, who preceded him and who first showed how much remained to be done. When he began, about a hundred of the nebulae were known, catalogued by Messier and a few others; by the time he finished, he had added nebulae by the thousands, and noted their astonishing variety.

The region chosen by Wolf for analysis is the so-called Cygnus Loop, now recognized as a supernova remnant. Wolf correctly shows by star counts that the obscuration here is caused by dust rather than by gas.Google Scholar
