M78 and LDN 1622, facing off across Barnard's flaming red wall, in HaLRGB

Orion is a fun part of the sky. I haven't imaged M78 or Barnard's Loop for several years and thought it would be fun to revisit this area with my new travel rig, the Esprit 100 and AM5. I used the NBColourMapper script to blend the starless Ha data into the starless RGB image and also to blend the starless luminance channel with a starless grayscale version of the Ha image... then brought them all together and added in the stars. This script makes this kind of thing surprisingly easy. I love the interplay between the Ha signal and swirling brown dust around M78 and LDN 1622, and the motion in Barnard's Loop. There's a lot going on here!

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.
