Orion Nebula HDR attempt

HDR attempt of the Orion Nebula from the end of Jan. I tried doing the noise reduction while linear and not overdo it, probably could have done with a bit more on the background.

Made from 17x 120second, 32x 30second, and 27x 10second images.

Didn't use the 60second or 1second images taken as I saw no difference or it would fail the HDRComposition.

Description: Integrated 17x120second image for comaprison with only AutoSTF applied. Nearly stuck with just this as is.

Description: Second attempt for better noise reduction from a guide by Jon Rista. Mainly using TGVDenoise, and MultiscaleMedianTransform during linear. Also had a try with masked stretch briefly.
A step in the right direction, particularly with noise reduction. I need some more practice with HDRmultiscale and LHE though

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.
