And finally it happened!!! It happens about twice a year to have good seeing at my place, not so frequently but better than never... These conditions allowed me to get good details of this wonderful and highly photographed object.
A wonderful aspect of deep sky astrophotography for me was learning the processing techniques, even if I enjoy the more capturing photons because it deals with the instrument, the collimation, the acclimation of the optics etc... In this phase of learning that never ends, I have had the privilege of receiving advices and teaching from people who produce magnificent works and who did it for the pure spirit of sharing a passion. Marco Lorenzi, Jeffbax Velocicaptor, Bruno Monteleone, Tommaso Massimo Stella come to mind. In this specific case I have to say thank you to Stephane Gonza (Exaxe), who in my opinion produces some the most beautiful amateur images of planetary nebulae that can be seen, for all the suggestions I received to compose this image.
First I made a LRGB with about 12.000 1 sec frames for the luminance to which I added the color obtained from about 8.000 images in H-alpha and as many in OIII (R/Ha - G/40%Ha-60%OIII - B/OIII). Then I added the H-alpha and the OIII channels with the method learned from Marco Lorenzi to compose this L-RGB-Ha-OIII.
I hope you like it. Recommendations on how to improve it are strongly accepted.

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.
