Creating the Images
Most of the images produced at the Lick were recorded as negatives on glass plates coated with photosensitive chemicals. After working through the night, astronomers often continued to work into the morning, developing the negatives they had created. They often found that the images were overexposed, underexposed, or blurry. We have in this archive only a few of the thousands of images created by Lick astronomers, as many were rejected. Many of the original glass negatives created with the telescopes are still housed on the grounds of the Lick Observatory.
