Simeis 147 - Spaghetti for 3 Years

So, finally, this is it! - I have been chasing after Simeis 147 for three years now!

It was in 2021 when I first started with a OSC-camera, but I discarded the data because I was not satisfied with the quality of the narrowband images.
So, trying again in winter 2022 and 2023, with a mono camera, with a total of 10 hours of exposure time for Ha and OIII each.
This was processed as HOO with RGB stars.

Since this is a 2-panel mosaic at 550mm focal length, the total integration time amounts to just over 45 hours, collected during 16 nights, making this my longest deep sky project yet!

Simeis 147 is a supernova remnant between the constellations Taurus and Auriga and goes by the popular nickname “Spaghetti Nebula”. The supernova causing these twisting filaments of shocked gas is believed to have occurred some 40,000 years ago. At a distance of 3,000 light-years this stellar debris cloud spans 150 light-years across, covering nearly 6 full moons on the sky.

If you look closely, it seems that some filaments with jagged edges are obstructed by tiny clouds of dark dust. This could be mistaken for a low signal to noise ratio or sharpening artefacts, but, since I took all exposures during new moon, I believe this is genuine.
What an amazing beast!

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.
