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.
