Mars - a lonely planet

Acquisition type: Lucky imaging

Mars last evening and I had very good seeing. At the zenith it must have been outstanding, but down there at 35 degrees, the altitude of the planet, it wasn't quite so good, but still by far the best conditions I have had for quite some time. This is a classic view with Olympus Mons quite central and just on the right side of the Meridian (central north-south line). Olympus Mons is the biggest volcano in the solar system at 22kms high.......compare that to Mount Everest at 8kms high. The diamond shaped scarp around it is readily visible. There appears to be considerable cloud around the Tharsis shield volcanoes further south and towards the terminator at right. The lovely north polar cap is resplendent at the top of the planet in this image. Ironically, for so many years I was looking up at Mars' bottom....its south polar cap, but now it has rotated down so we see it more from the top.
This is my favourite planet....so interesting.

I showed this rather small since it is not even quite 13 arc secs across. Against the black of space it struck me as a lonely place.

The capture parameters are presented in Version B as is a IR 642nm BP image at the same timestamp.

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.
