My Pelican inside the Swan

Finally I have managed to put together al the elements for this object. Capturing data was, in this case, the easy part. Along some nights in May and June I managed to get a lot of hours (I think it is my longest integration). All of them were captured from my backyard at the outskirts of Madrid (Bortle class 6 area), narrowband is kind of magic I must admit.

But processing has been a tedious journey, I wanted to squeeze all the juice of all that data, so I have taken many attempts, going all the way to the last part only to find something that I was not happy with or that wasnt up to the quality of the data. It is funny how sentitive is processing to initial conditions (as if it were a nonlinear or chaotic process)... starting all over to solve something was leading me to different results with new aspects to solve.... interesting journey....

Eventually I have managed to come up with this result, of which I am specially happy about the details in the dark nebula and dust "winds", the dynamic range in the dark areas and of course to check that even though I was using the Esprit 100 I managed to capture with some detail the HH-555 and other HH objects (only visible in the enlarged view).

(EDIT) I forgot to include that color is a variation of SHO with these config:

R=0.9*SII+0.3*Ha

G=H+0.6OIII

B=OIII+0.3Ha

I ended up on this config adter serveral tries to: 1) not to let bloated SII stars rule the starfield, and 2) achieve a "natural color" on the stars.

Hope you like it and any comment is welcomed!

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.
