M31 - New version from old data

I actually took the data for this in September of last year. I had posted a version at that time that I took with my ASI533MC color camera. That came out nice but was fairly grainy. I shot this with my ASI294MM and a set of LRGBHa Optolong filters. I was not really sure how to post process this image at the time so I just held on to the data. Another issue is the flats, especially on the Luminance data, was not great and had some left over artifacts that when I first tried to process this image it was quite ugly. I've since readdressed the data and with the help of Adam Blocks videos I see where I was having some issues. This still does not have the details I would like in the Ha parts that I know are there but I'll leave that for another day. I could keep working this data or just take some new data. I'm opting for taking some new shots for next time.

Overall I like this much better. Darker background, less noise and some nice subtle colors on this effort. I really like the ASI294MM camera. It works quite well. There is some very minor amp glow you can see on the raw data on the left side but it was processed out on the finished image.

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.
