The Great Orion Nebula

The Orion Nebula, also known as Messier 42 is the nearest star-forming region to Earth, located approximately 1,350 light-years away. The nebula can be seen with the naked eye as it has an apparent magnitude of +4. The Orion Nebula is part of a larger stellar network — the Orion Molecular Cloud Complex (also known as the Orion Complex), one of the most active star-forming regions visible in the sky.

I started collecting data in 2016 but between weather and life, I never finished gathering what I had originally intended. I decided to process what I had collected and was quite surprised with the result. Despite only 3.5 hours of total integration the data yielded a favorable result. I used a HDR blend of 5, 10, and 120 second exposures in RGB with 600 second exposures of Ha data obtained from my backyard in late 2016.

Total RGB= 62.5 minutes
Total Ha = 150 minutes

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.
