- The first orbital Hasselblad photograph of Apollo 8's Magazine 13-E (AS8-13-2215) shows an oblique southward looking close up of bowl-shaped crater Langrenus D (Al-Marrakushi) in the southern part of Mare Fecunditatis.
- An interesting mosaic (AS8-13-2215 to 2227), created by David Woods and Frank O'Brien of the Apollo 8 Flight Journal, shows the location of Al-Marrakushi related to the known region of Goclenius and Colombo (southward looking view).
- Al Marrakushi's odd surrounding high-albedo streaks (ejecta rays from Langrenus) are noticeable on several oblique south looking frames made by the orbital Mapping/Metric Fairchild camera of Apollo 15. Of these, AS15-M-2533 shows Al-Marrakushi near the centre of the frame.
- Oblique southward looking close up photographs of Al-Marrakushi were also made during the mission of Apollo 16, such as orbital ITEK-panoramic frames AS16-P-4442 and AS16-P-4447. In both frames, bowl-shaped crater Al-Marrakushi is noticeable near the left margins. Note also the bright ray-like material from its larger neighbour in the east: Langrenus.
- Apollo 16's Fairchild camera frame AS16-M-0671 shows Al-Marrakushi slightly to the left of the frame's centre.

- Named for Abu `Ali al-Hasan Ibn `Ali al-Marrakushi (fl. c. A.D. 1281/1282), a Moroccan astronomer and mathematician.
- The name Langrenus D was part of the original IAU nomenclature of Blagg and Müller (Catalog Entry 4691). It was attributed to Mädler.
- This replacement name for a formerly lettered crater was provisionally introduced on LTO-80D2 (Nov. 1974), for which it served as the chart title. It was approved in 1976 (IAU Transactions XVIB). - Jim Mosher
