M78, Barnard´s Loop and LDN1622 in Orion

LDN 1622 is a dark nebula in Orion.
It is known as the Boogie Man Nebula due to both its shape and its dark color.
the obscuring dust of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away.
At that distance, this 1 degree wide field of view would span less than 10 light-years

The M78 nebula is a reflection nebula in the constellation of Orion, one of the brightest diffuse reflection nebula in the sky.
This nebulae belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth.

In between both targets is part of the Barnard´s Loop, which surrounds Orion´s Belt and the Orion Nebula (M42).

The technique I used was to blend starless versions of an OSC RGB image and an OSC Duo-narrowband image.
These Two images combined formed the final RGB image which was then combined with the Luminance acquired with another setup. Stars came from the RGB OSC image.
Both setups were running in parallel and for this reason I was able to acquire 13h worth of data in one single night.

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.
