M106 - with(out) Aurora borealis

Revision title: Final denoise GraXpert v3

Alas I have no pictures of the great Aurora of 10 May, apart from this small offering. I was busy trying to capture M106, and struggling with what I assumed must be high haze, but was likely bright auroral activity - alas I was using a mono camera, shooting luminance!

Anyway with less then half an hour’s usable data, I was able to capture a surprising amount of detail in M106 and it’s bright neighbours. I used my Baader UHC-L filter, which gives a nice boost to the core.

Pre-processed in Sirilic, then in Siril after attempting removal of some very strange gradients (Aurora) in GraXpert. The resulting data were binned to boost SNR, and tidied up in Startools.

Description: This AI denoising tool was designed and developed using linear data, but I find works very well on the final stretched image too, removing unwanted processing noise.

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.
