North America and Pelican nebulas - 20211016 - Samyang 135mm at F2 - UHC - R channel

On October 16th, 2021 I took 137 60 seconds exposures of the North America and Pelican nebulas region with the Samyang 135mm open at F2 and the Canon EOS 2000D set at ISO 100 on Nebulosity.
I used Nebulosity instead of APT to use the bin 2x2 feature during acquisition and have smaller files to manage.
However, it looks like 60 seconds at F2 are too much for my city skies, even with an UHC filter.
Perhaps the focus was also a bit imperfect too and surely the almost full moon did not help either.
Anyway, by splitting the channels with Astro Pixel Processor and by stacking only the red one, I could create a monochrome image that emulates an H-alpha filtering and gets rid (mostly) of the noise due to the other channels.
This way I was able to somewhat salvage what would otherwise be a waste of time and effort.
Nevertheless the quality of the final result is rather shoddy and it proves that shorter exposures or narrower filters must be used at F2 from the city.

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.
