Some remarkable craters to the east of Mare Imbrium

I was going to post these photos separately, but with the work to be done accumulating I found to make this simple mosaic.

This image captured with ASI 224 shows the eastern side of Mare Imbrium.

The flooded Archimedes crater (83 km) is the dominant feature in this area and the largest crater in Mare Imbrium. It has a depth of 2.1 km and the two largest internal cratereletas, T on the left and S on the right (in the shade), have both 3 km in diameter. Montes Archimedes stands out remarkably in this photo with the sun at low angle as well as Rimae Archimedes and several other rhymes scattered pla landscape.

Autolycus (39 km) is to the east (on the right); It is a deeper crater with a depth of 3.4 km. Luna 2, the first probe to reach the Moon in 1959, landed (fell) between Archimedes and Autolycus.

Aristillus (55 km) is in the upper right corner. This crater has beautiful terraced walls and a complex group of central peaks rising up to 0.9 km above the floor of the crater, peaks that I have been able to highlight in all its beauty in this high resolution photo. Aristillus is a relatively young crater, it is the center of a very apparent ray system in the Full Moon. The basalt plain between these three craters is called Sinus Lunicus, although it is simply part of the same basaltic plain as the surrounding Mare Imbrium. A flooded crater (indicated by arrow 1) in crescent-shaped remnant, Spurr (13 km) can be seen approx. 40 km south of Archimedes as well, on the outer walls north of Aristillus there is a remnant of ghost crater. This is the protruding ledge (indicated by arrow 2) of an old crater that was almost completely submerged by the lava flows of the surrounding Mare Imbrium. The southern edge of the border was covered by the ejection of Aristillus.

Anyway, a nice photo in which one can appreciate many remarkable formations!

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
