These are the first photographs of a comet, taken at Harvard College Observatory in 1858. This is Donati’s Comet, one of the brightest comets observed in the 19th century. You can read about the process of photographing the comet, and early telescopic photography in general, in this article from the Journal of the History of Astronomy.

These images are from Account of the Great Comet of 1858 (1862).
