Description: I thought this might be a nice drizzle target. A drawback of the drizzle feature is, I've heard , you can't perform deconvolution. Neither, it would seem, HDR composistion.
When I ran HDR comp the masks had none of the core showing, only the larger stars appeared. As you can see from the core in C: The subsequent HDR multiscale also failed to reveal much detail within the galaxy.

Description: This is the original Image A: registered to the Drizzle image C: The idea being to add the deconvoluted and HDR composition core into the drizzled image.

Description: The blend of C: and D: using pixel maths Min Max equasion. In the top bar add. $T being the image you apply the maths too. I renamed the other image LHE

(min($T , LHE) + max($T , LHE))/2

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.
