M42 Extreme HDR (H-alpha)

This image is a bit of an experiment, playing with the high dynamic range mode of a QHY600 camera. The goal was to try to show in an image all of the features of M42/43 and the Running Man, from the small stars around the Trapezium, to the faint wisps of gas and dust surrounding the area. For this I did two series of subexposures. One with the camera in high dynamic range mode (13.8 stops) and with exposures such that no stars were saturated in the trapezium (100 sec), and another with the camera in my usual deep space mode and taking 5 minutes exposures. They were both combined, such that the core is basically the first stack and the rest is a combination. The final result is a bit weird, and possibly too flat, but lots of details are visible.

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.
