Simeis 147 The Spaghetti Nebula

[Andy Elliott]

Happy New Year everyone from the UK.

Simeis 147, also known as the Spaghetti Nebula, is a supernova remnant straddling the border between the constellations Auriga and Taurus. The nebulous area is large and has an almost spherical shell and a filamentary structure, which is difficult to observe due to its extremely low surface brightness

This has been one of my autumn / winter projects this year using my wide field set up, and I think it’s time to call it a day (or night). Just over 36 hours of dual band (Ha / OIII) data, and still just barely seeing any OIII. More data would probably clean it up a bit, but it’s time to move on. It has been quite a challenge to process, with several iterations before I was happy.

This version was created following my usual PI workflow but using the new Multiscale Adaptive Stretch process in Pixinsight, rather than Generalised Hyperbolic Stretch.

Taken with the Samyang (Rokinon) 135 and ASI2600MC OSC camera with the Askar C1 (Colour Magic) dual band filter.

Wow Andy, this is awesome! As I was going through my images for 2025 I came across this same nebula that I captured with the same set up as you. My spaghetti though came out much thinner than yours. It shows the difference between 8 hours and 36 hours worth of data.

You did a great job!

Thanks Jim. 36 hours is quite a commitment on a single target for me, considering the lack of imaging time over the autumn and winter so far. I'm sticking with the wide field for the next target, which will be the Cone nebula and Rosette nebula; hopefully won't require 36hrs!

Headed over to AB for a proper look and a reply. This is very nice, impressive with results coping with the hit to QE that you take using a OSC. I will have to capture this someday - hard to do with remote setups that have to be changed over to a WA optic. Until then I will enjoy this excellent result

That would be a fun target. I think I have seen that once before and thought it was really cool.
