Mars - 12 Dec 2022

Revision title: More sharpened

Acquisition type: Lucky imaging

Continuing my series of alightly different views of Mars, which is still displaying 100% phase just a few days after opposition. Tithonius Lacus, Noctis Lacus and Solis Lacus are front and central; to me Tithonius Lacus & Noctis Lacus look like ET's pointing finger. The polar hood remains strong, Olympus Mons is just rotating into view at the 10 o'clock position and there is morning cloud over the SE limb.Conditions were very frustrating, promising better than I could muster most of the time. Seeing wasn't great, not terrible, but I couldn't get the rig to hold focus more than a couple of minutes, which I suspect was due to temperatures continuing to fall - it was -4C by the time I gave in and I was very cold.Ideally I wanted to de-rotate 3x3 min runs, but I could see that focus had deteriorated significantly, even after 2 consecutive runs. Hence, despite me spending the best part of 2 hours in increasingly freezing conditions, this image is the best 10k frames a from a single 3 min SER captured mid session. Despite me constatly checking focus, the other 18 SERs that I captured just wouldn't give me anything good enough to keep.

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.
