NGC2244 – Rosette Nebula or is it a Skull?

This is a "first-time image" regarding two aspects:

The first (and most important) is using my new Optolong L-Ultimate filter. I own the L-Extreme, which gives 7 nm bandwidth for Ha and O3. The L-Ultimate is just 3 nm and is great for light pollution and the moon (at least somewhat). Unfortunately, my location worsened from around Bortle 4 to a clearly Bortle 5 on its way to Bortle 6 (thank you to the biggest local company, which decided to change all of their lights to LED to save energy instead of just dimming them -.-).

The second is the use of the "XTerminator suite" (BlurXTerminator, NoiseXTerminator and StarXTerminator). These PixInSight plugins are an amazing time saver and give great results "out of the box".

In general, I am happy with the details in the nebulosity because this object doesn't even reach 45° altitude at its peak at my location and the biggest light pollution "bell" is in the southern direction. As you can see, the stars are egg-shaped and not what I would consider "good". But that doesn't matter too much in this case since I am waiting for a clear night (with not too much moonlight) to get some time on that target for RGB stars, which I will place instead of those blueish narrowband stars.

I am also still working on my personal "standard" for dual-narrowband colouring of the resulting HOO images. Maybe a bit redder in the darker/orange parts of the nebulosity? I will see ;).

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.
