The subs was taken by Mr. Niels Haagh in the city of Ganloese, half an hour drive by car from CPH DK.

The TTS 160 Panther mount with the telescope rOTAtor was used.

Celestron C9.25 Hyperstar F/2 scope/setup and camera ZWO ASI071MC pro. used (my camera and 2" filter :-)

A 2" Baader UV/IR block filter was also used.

A Televue TV-60 scope used for guide purpose, the tracking scope was ZWO ASI224MC.

The PS, CCDStack2 & Registar processing part was done by me, and Niels H. did the calibration & stack of subs in PI.

The M42 core details / trapezium region was taken from this image,

One of my old M42 images

When I process raw image stacks I always store intermidiate results on the way to the final result, these images I can show to you all here,

Description: IMHO, it's a matter of taste.
I ended up with this final M42 color version.
I added a new color layer, with a given opasity in PS which was based upon (among other things) the DBE background extraction function in PI :-)
Note: Hmm, is the image mirror inverted?

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.
