Sh2-224 in SHO/RGB

Another major project of the Winter was Sh2-224. I tried this target two years ago, but was unable to get anything out of it. I started to take 5 minutes exposures but realized very soon that those are insufficient, especially for the OIII channel. So I switched to 10 minutes exposure time and kept on going for some time. Compared to the Dolphin nebula, this target is more accessible for me; hence I was able to collect a total of 37 hours, during a really nice long stretch of clear skies around the New Year.
I had to bump up the nebula quite a bit; I am really not such a fan of doing this, but without it would have been a very faint result.
Sh2-224 is a very faint supernova remnant located approximately 14,700 LYs away from us.

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.
