M42 The Great Orion Nebula and SH2-279 Running Man Nebula

When I started learning astrophotography last August, M42 was naturally my first object. I soon realized it is not an easy target to capture or process. I made many attempts and here is the result of five sessions, over five months in two locations. I also tried to process this image many times and eventually come to this one. I wish I could show more of the rich background and the subtle filament on the fringe of the nebulae, but with the extreme light pollution in my backyard, that's probably what I could do for now. The image was shot with 57x180s, 26x120s, 17x30s. I processed the stacked image with a separately processed stack of the 30s subs to create an HDR image in Photoshop so the core of the nebula does not get overexposed. Each of the five groups of subs was calibrated with 30 darks, 25 flats, 25 darkflats, and 50 biases.

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.
