NGC 2841 Tiger's Eye Galaxy widefield

NGC 2841 lies 46 million light-years away in the constellation of Ursa Major and has a diameter of over 150,000 light-years.
It is a prototypical flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous.

My process in Pixinsight :
Blink - SubframeSelector
(I had to throw away all my Luminance-data (2 hrs) as for one or the other reason the focus was way off)
WBPP
Dynamic crop on R,G and B
Gradient Correction on separate R,G and B
Channel Combination
DBE on RGB-image (as there were still gradients, worked in this case better than a second Gradient Correction)
SPCC
BlurXT
StarXT
NoiseXT on starless
Stretch starless
Curves on starless with range mask
Local Histogram Equalisation on starless
Stretch stars
Curves on stars
Combine stars and starless via Pixelmath (~((~Starless)*(~Stars)))
Add vibrance and watermark in Affinity Photo

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.
