On the map we see part of the northwest of the side of the moon that is facing the Earth, clearly depicted is the Gulf of the Dew (Sinus Roris). The craters on the edge of the area are most clearly visible around the full moon’s libration.

Crater (82Km / 48Mi Ř ) (84.6° W, 49.6° N). Circular formation situated in the zone of librations and overlapping Repsold. Few steep slopes. Few high walls supporting a crater to the South. Flat floor crossed by Rimae Repsold.
LANGLEY - Samuel P. Langley, Born in 1834 at Roxbury, USA - Died in 1906 at Aiken, USA. American astronomer and physicist. Inventor of the bolometer in 1881. Measured the atmospheric permeability to the solar light. Constructor of a plane in 1896. Determined the permeability of the atmosphere for different wavelengths of the solar spectrum.

MARKOV - Andrei Andreyevich Markov (Андре́й Андре́евич Ма́рков) Born: 1856 in Riazan - Died: 1922 in Petrograd. Mathematician. Demonstrated inequalities of Tchebychev in 1884. Specialized in the theory of probabilities.
Crater (43Km / 25Mi Ř ) (Dept: 2,450m /7,400ft) (53.4° N, 62.7° W) The rim of this crater is not appreciably eroded by impacts, and retains a sharp edge at the crest. The perimeter is roughly circular, with some minor outward bulges particularly along the southern and eastern edge. The inner walls are simple slopes that continue down to a ring of debris along the base. The interior floor has a low central hill and some minor ridges. There are no craters of note within the interior or along the rim.
OENOPIDES - Oenopides of Chios, (Οἰνοπίδης). Born around 500 BC in Chio - Lived till around 450 BC. Mathematician geometer and astronomer. Has measured the inclination of Ecliptic as compared to the celestial equator. He found this angle to be 24°, thus measuring the inclination of the earth's axis. Determination of the 12 signs of the Zodiac.
Crater (70 Km /41 Mi Ř )57.0° N, 64.1°W Heavily eroded by impacts, low outer rim that is hilly and contains a few clefts. There is a gap in the southeastern rim, and the level interior is attached to the lunar mare to the south. There are several small craters lying near the eastern rim, and the flat floor of lava has hills and craterlets. To the southwest is the remnant of Oenopides R, of which only parts of the rim are still protruding above the surface and the southern rim is completely missing. Few steep slopes riddled with craterlets and crushed by Babbage to the North-East. Few high walls.
