Cometary knots in Helix (with great seeing)

Revision title: Knots

Helix in SHO, with new camera and under excelente conditions.

After a long hiatus, I decided to get a new camera and revive my love for astrophoto, and this time everything collaborated: the equipment, the weather and even the seeing which was rather spectacular (very much needed for the 2.3 μm pixels of thenew camera). So I had the chance to test in on my beloved Helix, and couldn't be more pleased with the results.
To help cleaning the image I added data from previous sessions with the ASI1600 and even an uncooled 183MM.
My process was focused on the cometary knots, and not in the surrounding areas and extended halo.

Around 30hs from Bortle 9

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.
