A favorable Libration

I was again lucky enough to catch a favorable libration near the lunar south pole. It stands particularly Hale , a very hard to see and Demonax , Boussingault , Helmholtz , and Boguslawsky Neumayer crater.

The event is due to libration not perfect timing on the rotation and revolution of the moon that allows us to see around 9 % of the lunar surface ( the boundary zone of the hidden face ) opposite the Earth , which is invisible when we observe the Moon our position on Earth . The libration is due to displacement ( sway ) , real or apparent , of the lunar axes in relation to their average positions . Therefore this '' staggering '' Moon allows us to see 59 % of its surface at certain times. These moments of maximum libration libration that alternate between North, South , East and West , is in latitude or in longitude , offers us an interesting opportunity to make comments and pictures of these lunar regions still unknown to most of us.

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.
