Sh2-240 Spaghetti Nebula 
We are delighted to share a new project from our group that has kept us very busy. Here is a mosaic of two panels taken from the magnificent Texan sky at our former remote observatory, featuring the beautiful yet extremely faint Spaghetti Nebula.
Processing Choices and Colour Palette
The distinctive feature of this image lies in the choice of colour palette. We wanted to avoid the classic HOO combination, opting instead for a blend of HaOIIILRGB. This approach allowed us to highlight the wide-band dust (L, R, G, B) present in large quantities in the area, whilst keeping the faint filaments in Ha and OIII clearly visible. Naturally, to preserve the natural and correct colour of the stars, we used only the RGB channel data.
Notes on the object
The Spaghetti Nebula (scientifically known as Simeis 147 or Sh2-240) is a famous supernova remnant located in our galaxy, on the border between the constellations of Taurus and Auriga. This glowing remnant lies approximately 3,000 light-years from Earth and extends across space for about 150 light-years.
It is the result of a catastrophic stellar explosion that occurred around 40,000 years ago. At the centre of the nebula lies a pulsar (a rapidly rotating neutron star), which is the collapsed core of the original star. In the Earth’s sky, it occupies a vast area, equivalent to about six full moons.
