Spaghetti nebula, Simeis 147 (Jos Henrichs)

Spaghetti nebula, Simeis 147

The intriging Spaghetti nebula (Simeis 147 or SH2-240), only known since 1951, is a rather faint supernova remnant mainly radiating Ha light in the visual spectrum. It is located in the constellation Taurus. The dimension is 3°, 6 times the full Moon diameter.During an extreme long period of bright weather in March (for the Netherlands) I gathered in total 12h10m in 146 subs of 300s during 4 consecutive evenings from my backgarden (with a good view of the Southern sky). This was just enough to reveal some of the radiated OIII light. After basic preprocessing in Siril, I used Photoshop to get some interesting colour variation in the nebula by increasing the OIII information in the G and B channels and decreasing the overwhelming Ha signal. Starnet++v2 was very useful to extract the stars in order to process the nebula itself. I made the stars smaller before adding them to the final picture of the nebula.

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.
