Bailly and Hausen - September 14, 2020

Acquisition type: Lucky imaging

Moon 3 days and 8 hours before the new moon, September 14, 2020. For three days, when the south-west libration was deepening (W-6.8°; S-4.3°), I was getting ready for this sight - here is the remarkably plastic Bailly, behind him Le Gentil and Drygalski, and on the right Hausen with a subtly outlined crest of shadows at the west crown. It is Hausen that benefits most from the large southern libration, otherwise it would not be visible. The area has traces of the "great demolition" that took place when a large asteroid crashed into the lunar surface to form Mare Orientale. You can see radially arranged ditches, ridges, chains of craters.

The concavities of the polar regions are opposed by the convex crater of Wargentin marked by accident with the sign "X". Next to it, there are two other massive shadow craters: Nasmyth and Phocylides, and the vast Schickard, which, however, gives way in size to the 300 km long "walled plain" of Bailly (an old euphemism for a great 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.
