Mosaic in Cygnus - Propeller Nebula to the Tulip Nebula

A mosaic that I began by accident turned into 5 panels framed so different that anyone who looked at them would say I didn't know what I was doing. They would be right! If I knew I could do mosaics I would have tackled this a lot differently, and so next time I attempt one I will. Most panels were 4 hours each, the Sadr Region / Crescent was just over 6 hours and the filler to the right of Sadr and below Tulip in this framing was almost 3 and a half hours.

I stacked each panel separate in Deep Sky Stacker then combined the stacks in Astro Pixel Processsor. I then processed the linear combination in Photoshop. I originally attempted to process the stretched combination from APP, and though the result was okay, this felt a lot better.

Processing consisted of color balance levels, curves, NoiseXterminator for noise reduction and Astrophotography Tools Actions for deep space noise, space noise and contrast.

All data was taken over the past two weeks except 4 hours of the Sadr Region which was taken last year.

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.
