M42 Orion over 2 clear nights

Revision title: Shrunk file to acceptable size ...

Finally we had clear skies again end of Feb and first days of March, even though under a bright moon.

Used that to visit Orion again with the aim of several hours of exposure on several nights, as between nightfall and Orion disappearing behind trees in the west I have only limited window of opportunity.

I shot with gain 100 frames of 1, 10, 30, 60, 300 and 600 seconds. The 1 and 10 secs did not add too mich value so I skipped them.

Processing was done with Pixinsight with WBPP, HDR of the different exposure masterlights, dynamic background extraction and BlurXterminator. CurvesTransformation enhanced the contrast, but I was more satisfied with the results of a gentle photoshopping for the final image.

Any feedback or advice on the processing is most 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.
