        Schickard (227 km), is a large crater next to Phocylides Nasmyth craters.
It is surrounded in many places of smaller impact craters. The most important of these is Schickard E located over south-eastern edge.

         Drebbel (30 km), is a small lunar crater that is located northeast of Schickard.
The edge of this crater is circular, with an outward bulge along the south-east rim.
The name of the crater comes from Cornelius Jacobszoon Drebbel (7 November 1572 - 1633). Drebbel was an innovator who helped develop the measurement and control systems, optics and chemistry.

         Lehmann (53 km), is a crater attached to the northern edge of Schickard. To the northwest is the crater is Lacroix (38 km) foto.There is a gap in the southern end that connects to the floor of Schickard. A rille runs along this valley.
Crater name comes from Jacob Heinrich Wilhelm Lehmann (1800 - 1863) who was a German astronomer.

         Nöggerath (31 km), is a relatively small impact crater. It is located southeast of Phocylides, and is headed north before elongation of Schiller. Nöggerath crater is not notable, with a smooth floor and a rim that is only slightly eroded.
The name of this crater comes from Johann Jacob
Noeggerath (10 Oct 1788 - 13 Sep 1877), which was a German mineralogist and geologist, born in Bonn. In 1814-1815, he became Commissioner of some of the Rhine provinces, and in 1818 he was professor of mineralogy and geology and then director of the Museum of Natural History and chief of mining department at the University of Bonn.
