Kepler between an ocean and a sea.

Acquisition type: Lucky imaging

The Ocean of Storms (Oceanus Procellarum), the largest lunar sea, here plunged into darkness, is a basin that has been the subject of laser measurements thanks to an altimeter deposited by the Apollo 15 mission. It was determined that the gradients did not exceed 80 m within a 200 km radius.

In contrast, the Sea of Rains (Mare Insularum) is the place where the clear trails of the radiant systems of Copernicus (crater not visible here) and Kepler intersect.

This area is also characterized by the presence of the most spectacular set of lunar domes, indicated on the annotated version, especially north of Hortensius Crater and west of Milichius Crater (Milichius Pi). These typical lunar domes have a summit crater.

This view gives off a dramatic intensity by the contrast produced between the darkness and the light that amplifies the force of the reliefs.

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.
