- D'Arrest was also photographed by Apollo 10. This crater was captured near the upper margins of Hasselblad frames AS10-32-4850 and 4851.
- A pair of good eyes could detect the location of D'Arrest on several north-looking frames made by Apollo 16's mapping/metric Fairchild camera, such as frame AS16-M-0831, in which D'Arrest's location is near the central part of the curved horizon, very near the couple of bowl-shaped craters Cayley and De Morgan.

- The shadows in LO-IV-090H indicate the east rim of D'Arrest is mostly 1300-1600 above the points on the floor at which the shadows end. - JimMosher
Heinrich Louis d'Arrest (July 13, 1822–June 14, 1875) was a Prussian astronomer, born in Berlin. While still a student, d'Arrest was party to Johann Gottfried Galle's search for Neptune. On September 23, 1846, he suggested that a recently drawn chart of the sky, in the region of Urbain Le Verrier's predicted location, could be compared with the current sky to seek the displacement characteristic of a planet, as opposed to a stationary star. Neptune was discovered that very night.
