pio11_v_bw_o_n (AC79-9111.4, poss. AC79-9111.5)
This Pioneer 11 photograph of Saturn’s rings, supposedly taken on August 31, 1979, at a distance of 943,000 km (585,950 miles) from the planet, revealed amazing detail (for that time). Although now crude & primitive, this historic photograph revealed a new feature in the Cassini Division (commonly referred to as the ‘Cassini Gap’ previously), new features in the A-Ring, the discovery of the F-Ring, and a new moon, then designated 1979-S1. Although some uncertainty exists, the moon was likely/possibly Epimetheus, named so in 1983, following higher resolution imaging by the Voyager 1 spacecraft, along with more refined orbital calculations. However, caveat to the above is a reference to Epimetheus (at an ‘official’ NASA website mind you) as 1980-S3, so call it whatever you want. Tethys is to the upper left.
As there appears to be no stand-alone NASA or JPL listing of this/these images, the above is best effort at compiling from the content available at the following:
The exact images, oriented horizontally, on page 123:
