How do you like your pasta — molto al dente (slightly undercooked)? Well, at over 75 hours, this rendition of the famous “Spaghetti Nebula” is anything but (undercooked).
The Spaghetti Nebula is formally known as Simeis 147, a dim supernova remnant in Taurus. It is a large object, spanning about 3 degrees, and is estimated to be 3000 light years away. Most renditions of Simeis 147 show only the red spaghetti strands, consisting of the predominant hydrogen alpha emission, but this version also shows the much smaller (teal) OIII component.
Technical details are as follows:
All data was acquired in 2017-2018 at MYHY Observatory in the Philadelphia suburbs using a Takahashi FSQ 106N @ f/5 with an SBIG STL11K on a Paramount ME. This is a 2 frame mosaic using Astrodon 3 nm Ha and OIII filters with 30 minute subexposures. Processing was as an Ha-OIII-OIII in Photoshop.
