Horsehead and Flame Nebula

My third attempt (third year) at imaging this beautiful piece of space.

Lots of problems with Alnitak's halo that I could not repair to my liking. I have traced it down to the L-eNhance filter (see the "Deep Sky Imaging Primer" page 82.

Fun and actually pretty lightly processed. Happy with the dark intersteller dust showing below the Horsehead!

Actually, the total integration was about 2.5 hours of 120 second lights at 0C and 3.5 hours of 180 second lights at -10C. I could not find how to enter two different light sets in the acquisition data fields.

Description: Complete reprocess with the main goal of improving the star quality (especially the large halo around Alnitak) and adjust the color of the flame (the red flame got to me).
Stars were separated in linear and stretched lightly with GHS.

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.
