So I started doing Sadr after Deneb and realised about 20% of the two images was overlapping. Said "why not".

In the end I had more than 2800 subs and 46 panels. The Sadr and Deneb panels are about 13 thousand seconds deep. I processed all that on a NUC which I haven't shut down for 3 weeks.

Because of overlapping panels, some parts of the image are more than 20 thousand seconds deep, while others as little as 300 seconds. Which is still a lot at f/2.8, turns out.

I did not use the Advanced form because it was so many nights, practically every other night between August 9th and September 10th. All subs were 20 seconds, ISO800. More than half of the subs were with in-camera dark frame subtraction. It was impossible to get good enough flats but with 2.8k subs it doesn't matter.

The full mosaic actually included δ and η Cyg but I didn't like the resulting composition.

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.
