M42 Orion and Running Man Nebula

Still a work in progress, as I noticed the next day that the core was saturated. Pretty happy with the rest of the shot though. I didn't even realize the running man nebula was there when I decided to take the shot.

30/10/30 bias/dark/flats - I took new 300" darks prior to the session at around 50 degrees f, and noticed a huge difference in the previous ones I took indoors at 70 degrees f.

Description: I went back out and gathered 20 60s subs at ISO100 (original was 20 180s subs at ISO800) to fill in the saturated core. I think it's an improvement, but I seem to have added some ringing artifacts to the brighter stars. I could probably fix that with masking or matching levels between the layers, but I think I'm going to call this one done and revisit this target next month with a new camera.

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.
