After getting the RGB data a few weeks ago, I had the chance to collect about 9 hours of dual narrowband data on this magnificient object. With some good fighting against noise, I was able for the first time to really pull out the outer Ha glow.

The processing was fairly standard using mostly SIRIL, astrosurface and GIMP, but also for the first time AstroDenoisePy.
SIRIL : stack RGB data and dual narrowband data, extract RGB stars and Ha and OIII layers, apply first stretch and remove gradients; produce background the HOO composition and remove stars from it;
AstroDenoisePY : cancel the noise in the darker area of the HOO composition;
Astrosurface : pull the outer Ha glow out;
GIMP : the rest of it (levels and curves on the starless and apply the star layer by addition).

I am very happy with this result. I hope that you enjoy it.

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.
