Thanks Andy. Barnard used the so-called Bruce telescope. This was compounded of three telescopes: a f5 10” refractor, a 6.5” f5 refractor and a 3” guide telescope. He took photos of the Milky Way and noticed the dark patches, which he then photographed systematically. This involved hours of sitting in a cold observatory manually guiding. Film camera of course.
