For some nebulas, there is no need for an in depth description, their beauty speaks for it :-)

About the processing, the objective of this work was to generate an image including both, the extremely bright region of the trapezium, as well as the very dim nebulas surrounding M42 and M43. I thus took 1 second, 5 seconds, 60 seconds and 300 seconds subs in LRGB and then generated a separate layer for each one of them. I then used SPCC to match the color of the stars and of the nebula. At that point I generated as many as 7 RGB and 7 L layer masks in PS, so to avoid burning the core while highlighting the very dim regions. Achieving the right contrast/brightness balance for each layer to avoid brutal light transitions was definitely very challenging.

I hope that you will enjoy this version. As usual don't hesitate to provide input and comments.

CS,

Nicola

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.
