Revision title: IC 434 - The Horsehead Nebula

Like for most astro imagers, the horsehead is on my target list since the very beginning. But living far in the north that target is most of the time low in the sky. When traveling to La Palma (Canaries) this year, I finally made it and invested 23 hours of recording HaLRGB on that target. I used the ASI294MM for the first time and recorded Ha and lum in bin1, and RGB in bin2. I am still struggeling to combine the RGB data with the luminance and Ha but it's getting better and learning new things is half of the fun. So there might be new revision later. this year. ;-)
I hope you like it. Clear skies!

Title: IC 434 - The Horsehead Nebula

Description: I reworked that image several times during the last days and tried to optimize the integration of the Ha and Luminance data while keeping the natural colors of the nebula and the stars. Finally, I did not add the Luminance data to the RGB. Instead, I did extract the RGB to CIE L* a* b and replaced the L channel with the Luminane data which is less noisy and provides better details. Huge thanks to Frank Sackenheim who describes that workflow on his Youube channel.
Hope you like the image as well.

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.
