Revision title: Tried something else on M42

M42 is one of the most visited objects in the sky and it is often my "go-to" object when I want to try out some new equipment or technique.
So last night I returned to M42 again to work on the workflow using different filters and electronic focuser.
As the moon was bright and close to M42 I didn't go beyond 120 sec per light frame and this morning I realized that my flats for that were useless.
So I did stack 55 light frames taken thry my Astronomik L-2, L-Pro and a experimental IR/UV-filter together with some bias and darks.

This stack is almost not processed at all after that - only some stretching - and I tried to see how and if I could enhance the core of the object.

It is obvious that I need to work on my focus-routine (the OTA was collimated in the beginning of the session) and I do need good flats.
The guidning wasn't perfect or even good (appr. 1,5") but that could be due to poor/quick polar alignment and the fact that the scope was standing on wooden decking.

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.
