Kepler 8.1°N, 38.0°W

Kepler is undoubtedly one of the most prominent craters in the Oceanus Procellarum region. It is a relatively small crater, 31 km in diameter, with terraced inner walls, central peaks, and an uneven crater floor. Kepler is the centre of a very conspicuous ray system and is therefore one of the youngest craters. The wall of the craters appears to be slightly hexagonal. About 40 km to the northwest, a volcanic dome is visible under low solar illumination and in larger telescopes. It has a small, eccentrically placed summit crater.

Encke 4.6°N, 36.6°W

Encke lies southeast of Kepler and is an impact crater about 28 km in diameter. The crater wall is distinctly six-sided and is broken on the western side by the small crater Encke N (3.5 km). Encke has a central peak, and the crater's floor is uneven and rough. When illuminated near Full Moon, it becomes obvious that Encke is covered by the ray system from Kepler.

Kunowsky 3.1°N, 32.5°W

The crater wall of Kunowsky (18 km diameter) also seems to be slighly six-sided. Kunowsky lies east of Encke. The crater's floor appears significantly smoother than that of Encke. Amost exactly in the middle of the floor there is a small crater. An arcuate chain of individual ridges begins north of the crater rim.

Maestlin 4.9°N, 40.6°W

Maestlin R 3.5°N, 41.5°W

Maestlin is a small round crater, with a diameter of 7 km and a depth of 1.5 km. South of it lies Maestlin R.
