Babbage crater on the Moon by astronomical telescope.

In front of Pythagoras (which is not seen here), we see a large crater named Babbage (143 km), one with a depth of 2 km.
The remnant crater named South, is entered in its southeastern floor.

Babbage's outer wall was eroded and modified by other multiple impacts until all that was left of it was a ring of rounded hills. Over the southern edge is observed Babbage E (68 km), whose northern edge is practically nonexistent forming a kind of golf within Babbage.

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.

Magnitude: -12.03
Phase: 70.5% (0% = new, 100% = full)
Distance: 398.311 km
Sidereal Period: 27.32 days
Illuminated: 92.2%

Optics: Celestron C8-Newtonian astronomical telescope 
Eyepiece: Plossl 20mm, 2x Barlow
Mount: CG5 (EQ5)
Camera: Sony CX130

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.
