My second failed galaxy image of the season. Conclusions:
1. Never image through haze and moisture.
2. Use a light pollution filter.
3. Do not let clouds confuse your autoguiding.
4. Take time for darks, flats and biases.
5. Galaxy imaging demands a clear and transparent sky

Though Siril is excellent in background extraction, calibration makes a big difference by evening background, removing sensor contamination and vignetting. Old school but recently experienced in practice. The latest additions to Siril, interface to Starnet2++ (CLI) and the new star size reduction script (courtesy PI developers) are working flawlessly (need Ver 1.2.0. Beta 2). Great stuff, indeed! Stacking in Siril, too, is painless and straightforward with its scripts.

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.
