Revision title: HorseHead III

I know there are lots of experienced dudes on Astrobin.

I am trying to learn PixInsight, if you experts can tell me how to go about removing the star halo of bad boy Alnitak (I understand he is well known for causing filter halos) it's appreciated.

The "front end loader" scope I use, RASA 8, is especially bad because the camera wires are visible in the reflection.

Description: Just mirrored original image to "normal" view. I am satisfied with the image apart from the amazing halo but Alnitak is bad news and notorious for it.

Title: 2022 Horse Head Nebula

Description: This year I used a different camera and filter, the NBZ Nebula filter. It did a much better job with bad boy Alnitak did last year using my RASA 8 scope. No huge halo!

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.
