One icy cold, clear and cloudless day after five damp, overcast and foggy days. Though the bare eye spots clear and crisp mountain tops, and snow covered north faces, the seeing is again at least as bad as it was five days ago. Having had some success last time with processing 1000 washy and blurred images and facing the next longer bad weather period ahead over the holidays, I decide to give it a try.

Having only 30 minutes left before the Sun disappears behind the birch trees, I hurry up to setup everything and start capturing. 10 minutes later I am ready to start my capturing session with FireCapture on my nice little Astroberry (Raspberry Pi 4). As expected, the SER videos look disappointing at best.

After converting the SER to AVI via PIPP, I stack the suggested selection of 5% from 1000 images for the first result with the very fine Planetary System Stacker (PSS). The TIFF gets sharpening and histogram adjustments in ImPPG, which is an excellent piece of software for the Sun, the Moon and the planetary post processing.

The final result is shown here. Please compare version B for an impression of the awful seeing.

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.
