2. Andromeda Nebula, photographed by Edward Barnard, 1894.
3. Great Spiral Nebula, photographed by the Earl of Rosse, 1899. This is a four-hour exposure of the Great Spiral Nebula using the 36" Crossley reflector. Astronomers did not yet understand the difference between nebulae and galaxies, believing that they were of the same nature. Most thought that all of these distant structures were contained within the Milky Way galaxy itself. The difference was confirmed in the 1920s; the work of one of the Lick's astronomers, Heber Curtis, contributed in part to this development.
8. Letter from Charles Perrine to Photogravure and Color Company, 1907. Perrine and the printers at the Photogravure and Color Company exchanged a series of letters regarding the difficulties of reproducing the glass negatives of nebulae created at the Lick. Printers used chemicals to "etch" the image of the original glass plate into copper plates. The etched portions were then filled with ink to create a print. Details of the original image were often lost in the process.
