- Ptolemaeus A (Ammonius) was captured on Ranger 8's Frame P002 (third photograph in this frame, at lower left).
- One of Apollo 12's orbital Hasselblad photographs of Ammonius is included in the book Full Moon by Michael Light and Andrew Chaikin. This photograph (AS12-51-7506, as Plate 43) looks almost the same as AS12-51-7507. Both photographs show the bowl-shaped crater Ammonius in the foreground, while the lunar module (LM Intrepid) is seen near the lunar horizon.
