Moon - Copernicus

Acquisition type: Lucky imaging

Copernicus is one of the most striking lunar craters with a diameter of 90–95 km.What is unusual about the impact crater is that it has not just one, but several central mountains that are up to 1.2 km high. The crater wall is clearly terraced and hardly eroded because it is one of the youngest major impacts on the moon. While the crater floor is about 3800 m deeper than the ridges, these tower over the surrounding plain only about 900 meters. Such large differences in altitude levels are rare.

Like the craters Tycho and Kepler, Copernicus is also the starting point of a radiation system that can be seen particularly well under this lighting situation like full moon. This system of rays particularly fascinates me in this picture. It gives me an idea of the tremendous energy that has been released during this impact. The disadvantage of this lighting situation however, is that a clear height structure is hardly recognizable and the picture appears flat.

Because Copernicus is very bright I had to reduce the gain to 81. Both the raw material and the quality graph of AutoStakkert! gave me no hope of a good image. I used 900 out of 5000 frames. Under these circumstances, I am still somewhat satisfied with the final result.

After sharpening with RegiStax I did the final image processing with Lightroom in terms of contrast and a little denoise.

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.
