Orion Nebula, de Mairan's Nebula and Running Man Nebula

Revision title: Revised with better treatment for Ha

Crop from a 4-panel mosaic of M42 and neighbors, rendered in HaLRGB palette.

Each panel consisted of 15 mins each of:
30s each L and Ha subs
60s each of R, G and B subs

There were a lot of objectives I was trying to satisfy with this image:

Keep the trapezium stars visible while not blowing out any nebulosity
Show the reds of Ha emission in Orion while retaining the reflection nature elsewhere
Keep the star in M43 visible without having nebulosity washed out
Show a bit of the greens and oranges that are seen when viewed with naked eye

*I think* I have hit on those objectives but, taking a step back, I probably feel as though there's some color cast too. Not sure if it's just me or it's something I need to rectify.

Anyways, I doubt this will be the last time I will be processing this data.

Clear skies!

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.
