Mars on December 30, 2020 (OSC RGB) - My Last Mars of the 2020 Apparition

Acquisition type: Lucky imaging

Imaged Mars in OSC RGB on the evening of December 29, 2020 (Dec. 30th in UTC). This was my final imaging session of the 2020 Mars apparition. Seeing transparency were both average on this night. Mars was showing a disc just over 10 arcsecs in diameter (89% illuminated) at magnitude of -0.3. The dark albedo feature near the equator and to the left of the meridian is Mare Cimmerium and to the right is Mare Sirenum. The northern polar hood is still just visible, but I was unable to capture the now diminished south polar cap.

Imaged with a C8 Evo, ZWO ADC, Baader UV-IR Cut filter, and ZWO ASI224MC. Imaging train was configured to give ~F/20 (~0.18 arcsec/pixel). Image capture using Firecapture with gain set at 300 and an exposure of 2.5 ms. Stacking in AutoStakkert3 (best 5% of ~70,000 frames captured over 240 seconds). Color balancing and Wavelet sharpening in Registax6. De-rotated and combined 4 images in Winjupos.

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.
