NGC 281 in SHO/RGB with more data

The backlog is empty now, this was the last set of data that I obtained over the last 5 months or so, and new ones seem to be very hard to come by, weather does not look promising. I kept this as last since it is an update/addition to the previously obtained data from 2021. Wanted to find out if combining datasets from different years will make a difference, and I think it does. Gathered another 20 hours extra on the Pacman, needless to say one of my favorite targets for backyard astro photographers. Spent quite some time on the image, really wanting to find out how far one can come with the new processing tools plus extra data. Cannot see that I could get more details out of this area unless using a higher magnification scope, which of course makes me want to have one 😊. Color assignments in SHO images always a matter of taste, I liked this version the best of all that I came up with during processing. The nebula itself actually extends quite far with faint wisps to the right in this image, which I was not able to show in previous attempts without creating an unacceptable noise level.

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.
