LO-IV-071H Steinheil is the crater in the upper left, overlaying similarly-sized Watt (to its southeast). The sharp-shadowed 6-km circle of Watt B can be seen on the south floor of Watt, with 10-km Watt A and 12-km Watt B beyond it (outside the rim). In the upper left corner of this view are 17-km Steinheil X and 16-km Steinheil Y (only partially visible).

Nomenclature
- Carl August von Steinheil (October 12, 1801 – September 14, 1870) was a German astronomer and physicist. He founded the optical-astronomical company C.A. Steinheil und Söhne to build telescopes, spectroscopes and photometers (his invention, used to measure brightness). In 1852 he added refractors and reflectors with silver-covered mirrors to the production.
- Whitaker (p. 200) notes that the combination of Steinheil and Watt was labeled Zamosci on van Langren's 1645 map. Whitaker does not explain where the name Steinheil came from, but evidently in Elger's day the entire structure was known by that name. The name Watt, for the eastern part, was apparently introduced by Schmidt (Whitaker, p. 224). - Jim Mosher
