To the trailblazing scientists and artists who more than 150 years ago used the newly invented medium of photography to record what was imperceptible to the human eye, the answer to that question must have seemed magical. At least, that's the impression I got while wandering through San Francisco Museum of Modern Art's "Brought to Light: Photography and the Invisible, 1840-1900." Organised by SFMoMA's associate curator of photography, Corey Keller, "Brought to Light" gathers more than 200 photographs, albums and ephemera to illustrate how science and photography revealed the invisible in the early 19th century.
An Astrophoto Setup There is a bewildering variety of telescopes available on the market. Refractors, reflectors, Newtonians, Schmidt-Cassegrains, Ritchey-Chrétiens and many more fill the pages of catalogues and websites catering to amateur astronomers. What is best for photography? The answer is not simple and depends on what you want to photograph and what your budget is.
