Mars on January 25, 2023

Acquisition type: Lucky imaging

Imaged Mars on the night of January 25, 2023 (January 24th in UTC) under average to below average seeing and average transparency. Mars' disc had a diameter of 11.5" and a visual magnitude of -0.5 at this time. In the southern hemisphere, Mare Sirenum is to the west of the meridan and Solus Lacus is to the east of the meridian. Olympus Mons is near the meridian in the northern hemisphere, but can't be discerned in this image. I thought I was all done with my Mars image processing for the 2022-2023 apparition, but found a folder of unprocessed data, so this is truly the last of it...

Imaged with a C8 Evo, ZWO ADC, Baader UV-IR Cut and IR685nm pass filters, and ZWO ASI224MC. Imaging train was configured to give me ~F/20. Image capture using Firecapture with gain set at 325 and an exposure of 2.5 ms. Stacking in AutoStakkert3 (best 10% of ~25000 frames captured over 180 seconds). Color balancing and Wavelet sharpening in Registax6. De-rotated and combined 3 sub images in WinJupos.

Original version: Mars in OSC RGB at 01:39 UTC

Rev B: Mars in IR at 00:55 UTC

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.
