description:

According to Tom Borlik this image was "...taken with a Kodak Hawkeye camera...in July 1959 by me while I attended the 1959 Indiana Science Institute at Indiana University. [This image shows] the comparator blinking machine used to compare photographic plates taken by the aforementioned (see image P0052614) 10-inch Astrographic Camera. The photographs were taken about an hour apart and so by looking at one of the plates and then flipping the mirror to look at the other plate that image of the asteroid would appear to jump and it was with one of these machines was located in Swain Hall West in Bloomington and the blinking program was done by a Mrs. Beryl Potter for many years and when she retired it was taken over by a Brenda Records and so accordingly, the last asteroid discovered with this camera was named by Dr. Edmondson - 'Records'."
