The predominant feature in these pictures is Mare Frigoris, a narrow strip located north of Mare Imbrium basin, identified by the darker area.
On Mare Frigoris and on the eastern edge of Sinus Roris, we see an isolated crater called Harpalus (39 km). This is a recent crater and has a depth of 2.9 km. As a novelty, is that its interior is visible, something I hadn't noticed the other nights. To the southeast is a smaller crater, Foucault (23 km), and to the northwest is the crater South (108 km). I also mention here in these images Markov crater (40 km).
The name of the crater Harpalus comes from Harpalus, son of Machatas, who was an aristocrat of Macedonia, which spent his childhood with Alexander the Great in the 4th century BC.
Craters were filmed with a video camera attached to an astronomical 203 mm Newtonian telescope.
In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
