Witch Head Nebula and Rigel - Ic2118

The Witch's Head Nebula and Rigel proved to be a real challenge in my astrophotography journey.
The many hours of integration were collected in the months of November, December and January under the sky (bortle 4/5) of my small home observatory on the Adriatic coast.
The processing was carried out using Pixinsight, and @Bill Blanshan 's pixelmath formulas for both mixing the ha all rgb and stellar reduction were decisive for the result.
The biggest obstacle turned out to be Rigel which, placed in the corner of my shooting frame, created some reflections due to my filters, especially on L,G and B.
The first versions of the shot had discouraged me a bit but also thanks to the precious advice of my astrophotography friends I came to this version that meets my expectations even if not fully.

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.
