Messier 42: The Great Orion Nebula

The Orion Nebula is one of those DSOs, like the Pleiades and Andromeda, that every new astrophotographer goes for early on. Nevertheless, I never grow tired of this gorgeous nebula. It is so complex and there is a lot going on in it. Two open star clusters radiate the energy that ionizes much of the gas. The mysterious "bullets" rocket out of the region. New star systems are actively forming within it. But the Orion is a demanding target to shoot. The Trapezium Cluster is exceedingly bright and outer regions are quite dim. I found a multi-layer approach to shooting and developing the complex was the best way to capture its full dynamic range. Fortunately, it is so bright that from my dark sky region it took only 16.33 minutes to capture all the subs. One second, 5 second and 60 second subs were captured to accommodate the Trapezium Cluster's brightness, the mid-range brightness of the middle nebula, and the darkness of the outer regions.

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.
