I found this one more difficult to process due to the very bright core within the Orion Nebula.

For this, I captured two sets of exposures and combined them as an HDR image using the HDRComposition process in PixInsight. This is only ~30 minutes of data, as I have a limited window of targets toward the south, due to trees being in the way. Will try and find a better place to setup the telescope next time, and hopefully capture more data. Might also try the L-Pro filter next time, to see how the colors come out.

To fix the overly bright core in this image I first tried using HDRMultiscaleTransform, but this kept washing out and destroying the color towards the center of the nebula, regardless of the settings I used.

So I instead used varying sizes of masks to gradually lower the highlights of the core in phases, with each mask getting smaller and smaller until I ended up with this result.

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.
