Description

Photograph of the photoelectric cell photometer attached to the 12-inch refractor. The photograph dates to about 1913-1915. During the summer of 1915, Dr. Stebbins took this photometer to Lick Observatory to study the variable star Beta Lyrae. Photographs of that photometer on the Lick 12-inch telescope match this photograph of the photometer on the Illinois 12-inch telescope.
