This is a photo of Mount Wilson Observatory or Opids Camp, California made from an original 5x7 inch glass or film negative between 1912 and 1930. If you have more information
about this or any of the others I have, please go to this page and send me a note.
Thanks, Mike Ryan
Polishing a mirror, note the base, it looks like a wood stove base to me.
"If the top picture is of a secondary mirror then it is for the 60-inch telescope.The optical shop was also on Santa Barbara St. in Pasadena. M.S. note.
This picture shows the 150-foot solar tower telescope (world's largest solar telescope at the time) and the dome of the 60-inch telescope." M.S. note.
