Rimae Sirsalis, Sirsalis and Hansteen Crater in natural colours

Acquisition type: Lucky imaging

A long-sought target of my lunar activity, Rimae Sirsalis was "in place" so I took the chance with good seeing. Besides, not many images on this target in Astrobin despite the interesting Lunar feature it is (an avereage 3-km wide rille run north-south on the eastern side of Sirsalis Carter. Rima Sirsalis is a fracture zone, possibly caused by the Orientale impact, and interestingly, it cut across various lunar terrains, including highlands and maria. To the south, Rima Sirsalis merges directly into the rille system Rimae Darwin )

Sirsalis is a crater 42 km across, with a central peak (hidden in the shadow in the image), it overlaps the crater Sirsalis A, 49 km across. Up in the image is the Hansteen Crater, a very interesting (a nice way of saying very fractured) although light was not perfect for this crater, overall in comparison with Billy crater (cut in the image).

The AP details are: a mosaic of 5 images, up-right, up-left, center, Bottom-right, bottom-left, cutting out the borders to focus on the central part of the mosaic. Each image is the best 1000-1500 stacked images out of around 50000 images captured at around 150 fps.

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.
