Altai Scarp from the OTHER direction

Acquisition type: Lucky imaging

Due to the vagaries of weather, my work schedule and sometimes needing to get that most annoying thing called sleep, all of my images of the Altai Scarp have been taken in the early evening, when the sun is illuminating the face of the scarp. Last night I decided to get up at 4:00 in the morning to image this area with the sun coming from the other direction. The sun from this angle creates beautiful shadows to the east across the flatter terrain at the base of the scarp. The scarp is 495km long, from Piccolomini crater at the bottom to Catharina at the top. It is about 1km high. The sun is coming from the top-left in this image.

As an aside, I continue to be blown away by the resolution of this new C14 EdgeHD

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.
