My take on the Vela SNR in NB.
It’s a huge and facinating region of space, with strong O3 & Ha present.
The S2 is only subtly different to the Ha emission line, so quite difficult to process to yield a true tricolour image.
That being said, I’m happy with this as last – inspired by marvelous versions from Strongman Mike Sidonio, Rakibul Hasan, Paul Haese & Marco Lorenzi.
Ha = R, O3 = B, S2 = G approx 6.5 hrs of each in 30min subs – total of around 20hrs.
Can’t help but think it reminds me of the Chalice from the Holy Grail.
About this Nebula
Vela Supernova Remnant
The plane of our Milky Way Galaxy runs through this complex and beautiful skyscape. Seen toward colourful stars near the northwestern edge of the constellation Vela (the Sails) the glowing filaments of the Vela Supernova Remnant are the expanding debris cloud from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago. In addition to the shocked filaments of glowing gas, the cosmic catastrophe also left behind an incredibly dense, rotating stellar core, the Vela Pulsar. Some 800 light-years distant, the Vela remnant is likely embedded in a larger and older supernova remnant, the Gum Nebula. (Apod)
