Presenting M42 using my beginner equipment and my modern equipment.

In this workflow, I realized that HDRComposition is mostly excluding a ton of data that should still be getting stacked into the main image. I decided to integrate all my HDR sub-masters before doing HDRComposition to gain benefits of that extra data to increase SNR.

Pre-processed using WBPP, registering HDR subsets by camera.
Registered all sub-masters to the closest field of view.
Combined all sub-masters using ImageIntegration.
Combined all sub-masters again using HDRComposition (note: 183MC_30s caused problems in HDRC, was excluded here).

Binarizing Threshold: 0.0500
Mask Smoothness: 22
Mask Growth: 2
Replace Large Scales: 0

Ran CreateHDRImage(layers: 6, Blend: 0.75, Intensity: true, Scaling: B3 Spline 5) to bring down the core.
Unscreen Stars
Used LHE to bring out wider core details.
Created range mask to exclude the brightest parts and keep all the dark surrounding areas.

ExponentialTransformation to boost the dark nebulae.
LHE to bring out more contrast in dark nebulae.

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.
