I found a nice bundle in my mail earlier this week. Some old slides and negatives mailed to me by Roger Carpenter. They are Palomar-related pictures that were taken by his father, an astronomer from Steward Observatory in Arizona.
I will post some others from time to time but this one really struck me because it:
1) arrived in my mail on August 12 -- 70 years to the day after it was taken.
2) is a rare color photograph taken looking into the Caltech Optical Shop while the 200-inch mirror was there.
This photo was scanned just a few minutes ago. Apart from some people in Roger's family, the visitors to Palomar Skies, are the first people to see this photo.
