An astronomer's beautiful pastel drawings of the cosmos from the 19th century

In the late 19th century, artist/astronomer itienne Li(C)opold Trouvelot (1827-1895) painted thousands of stunning works illustrating the beauty and science of the known planets, comets, and celestial phenomena. The Huntington Library near Los Angeles holds 15 of Trouvelot's chromolithographs that were published in 1882 in two portfolios, the Trouvelot Astronomical Drawings:

Initially, the Astronomical Drawings portfolios were sold to astronomy libraries and observatories as reference tools, but as early 20th-century advances in photographic technology allowed for more accurate and detailed depictions of the stars, planets, and phenomena, Trouvelot's prints were discarded or sold to collectors.
