NGC6979 (& other designations) - The Veil Nebula Supernova

These are the remains of a star that would have been 20 times larger than our sun before it exploded 10 to 20 thousand years ago. 

All that remains is hot ionised gas and dust. The explosion would have been seen from earth and would have been visible during the day due its brightness even though it is 2400 light years away. The Veil is still expanding and is currently 36 times the size of a full moon as seen from earth, although now too faint to be seen with the naked eye.

This is my most ambitious project to date. 

It is a four panel Mosaic with 25 ten minute exposures in each panel, all stacked together to improve signal and reduce noise. The blue colour shows Oxygen III gas whilst the gold is mainly Hydrogen alpha. The gases have been separated into shock fronts by the explosion, and solar winds, and now glow due to the intense radiation from surrounding stars. Processing this was a steep learning curve, and the massive 1.2GB image made it a slow process with even just saving the project taking 15 minutes. I may add more data in the future and reprocess it but for now I think it is finished.
