- A small unnamed irregular depression east of Wallach (at 5° North/ 33°45' East) was the centre of attention in Apollo 8's Landmark Tracking Exercise. A series of orbital photographs were made of it, the best close-up photograph of this series is AS8-13-2300.
The first frames in this series of photographs (of Mare Tranquillitatis) show the surroundings of that irregular depression, while looking westward over the remains of crater Maskelyne F. Bowl-shaped crater Wallach is visible in the distance (of which frame AS8-13-2287 is the best one; it shows Wallach near the frame's right margin). The last photographs of this series show the same region looking east, toward the same Maskelyne F. Crater Wallach is not visible in these last frames, because of a disturbing solar reflection effect in the Hasselblad-camera's lens system.

Additional Information
Depth data from Kurt Fisher database
- Westfall, 2000: 1.14 km
- Viscardy, 1985: 1.14 km
- The shadow in LO-IV-173H indicates a depth of 1170 m. LTO-61D1 gives the depth quoted by Westfall and Viscardy. - Jim Mosher
Nomenclature
Otto; German chemist; Nobel laureate (1847-1931).
- This replacement name for a formerly lettered crater was apparently introduced on LTO-61D1 (for which it served as the chart title). By the time that chart actually appeared (February, 1980), the DMA no longer followed its recent practice of avoiding names of lettered craters unless a non-lettered replacement name had been approved. - Jim Mosher
- Misspelled as Wollach on Map 1 in The Hatfield Photographic Lunar Atlas (Springer, 1999).- DannyCaes Jan 26, 2013
