Clavius - Blancanus - Scheiner - Kirscher - Klaproth - Casatus

An almost over illuminated Clavius crater in the centre foreground - being slightly further away from the terminator (in a brighter part of the moon) than the earlier Moretus crater post. Clavius is 231 km wide and is of Nectarian age (about 4 billion years).

There are 4 smaller younger craters that can be seen to have affected the terraced walls of the giant Clavius crater. The larger two of the four formed from later bolide impacts that slammed into Clavius’s crater walls are Porter (foreground, 52 km wide) and Rutherford (54 km wide) on the left edge of Clavius. Both of these, whilst much smaller than Clavius, were clearly significant enough to cause rebound of the excavated lunar crust resulting in local mountain peaks within the crater centres.

Behind Clavius in the background are Blancanus and Scheiner. Kirscher at centre top edge. Centre left edge are Klaproth and Casatus with its crater-floor crater.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
