The subject of this image, taken at a wavelength of 715nm by Schott RG-715 long-pass filter, is the lunar crater “Tycho”, one of the most famous impact craters visible on the Moon, whose rays are due to the violent powerful impact, it is even visible from Earth to the naked eye. To see the actual crater, you need at least a small binocular to return some magnification (typically at least 5x or more) compared to the ocular vision without any optical instrument.

Tycho is a crater with a diameter of about 85km and an estimated age of about 108 million years. The asteroid from which the crater was generated must have been almost as big as the one that caused the extinction of the Dinosaurs, about 65 million years ago.

In the image, which is oriented with the South at the top and has a resolution about of below the Km, you can see (from left to bottom, clockwise) the craters: Orontius (partial), Pictet, Street, Longomontanus (the one in the shade, at the extreme edge at the top right, on which the Sun is rising), besides obviously the Tycho crater exactly at the center of the image.

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.
