M42 - HDR

So, apparently this winter i am fated to study M42, so sorry for the repetition.

In this image, I am using new glass (Tamron 70-200mm) because my old lens suffered a fall ... sigh.

Then again, the new lens is SO MUCH BETTER.

Anyway, this is an HDR composition of 5, 15 and 40 second subs.

As for processing, there were some unique challenges around getting the HDR composition process in PixInsight to work (I had to manually rotate two of the stacked images to get them to register correctly) but it was a great learning process. Additionally, I finally had some success with noise reduction.

Critiques and pointers welcome.

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.
