This represents my first attempt at using PixInsight's HDR capabilities.

I actually shot this as LRGB + Ha, but in processing it, I felt that the Lum and Ha blew out the Trapezium far too much, so I wound up just going with RGB instead.

Still seeing some donuts around bright stars - probably a consequence of my (lack of) processing skills.

Description: Much better stars - no more dark halos, and a far better Trapezium.

For this revision, I applied BlurXTerminator at the very start of my flow, to my channel-combined linear image (as opposed to the very end of the process, after I was done with all of my various edits). Furthermore, I applied NoiseXTerminator just once as the final step in my flow (as opposed to multiple times throughout).

It helps to read the instructions provided by the process' author ... :)

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.
