Great Nebula in Orion, and the Running Man

FINALLY done with this one of the Great Nebula in Orion (ok and the Running Man). Despite its popularity, it’s one of my favorites, and is one of the brightest nebula in the sky: it’s visible to the naked eye, as the second star down in Orion’s “sword”, hanging from Orion’s belt. It’s about 24 light years across, and an active stellar nursery. From an image processing perspective, this is one of the most challenging images I’ve done: it’s a 4 panel mosaic, comprised of differing exposure lengths blended together to produce an HDR effect for each of the four panels, which were then stitched together. I also got some Ha data, though it didn’t really add all that much, given how bright and detailed this target already is. Regardless of the HDR processing, I still kept the core as bright as it is because I always think it looks kind of flat when people process it just to bring out the trapezium stars that comprise the core. It’s taken FOREVER, so I’m glad to be done with it: I have a backlog of other imaging data to process, including M81 and M82, Flaming Star, and Melotte 15 (which I’m most excited about).

Description: Added a little more detail into the core, applied some more noise reduction, and made a handful of curves adjustments to bring out a few more highlights

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.
