Orion and Running Man Nebulae

I was inspired by Warren Keller's PixInsight talk at AIC 2019 to finally learn PixInsight, so this is my first serious attempt at using it. I must say the calibration, noise estimation, and noise reduction facilities are far superior to any other tool I've ever used (somewhere around a dozen since ~1990). The photometric color calibration is really impressive too. Revision A is a cropped zoom of the full image that I found particularly pleasing.

Loads more to learn about PI and lots more that one could do with this data. I am impressed that this is only 9 images each of RGB. Certainly, the very bright nebulosity got the photon noise and mean well up above the read noise, which helped PI with noise reduction in the bright areas -- this is particularly evident if one performs a hard stretch and looks near the corners of the image and is also evident in the noisier dark, dusty region between the two nebulae.

Oh yeah, this was taken when the Moon was nearly full...!

Description: Haven't yet figured out how to stretch and preserve core detail in a way that is satisfactory to me. The Trapezium is in there, as are some nearby fainter stars that have some really nice color contrast (e.g., orange and blue). There are some other image processing things I’d like to do better, including contrast.

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.
