A spectacular cataclysm - The Vela SNR

Image Description and Details : Vela Supernova - one of the most famous and beautiful “celestial cataclysm” located in the constellation Vela. Supernova remnants are the leftover results from the explosions of massive stars into supernovae.

Since Vela SNR isn’t visible from the North hemisphere where I live (Switzerland), I grab the data from the Heaven’s Mirror Observatory located in Australia. I am grateful for the data even though the pre-processing part took me quite a while to meet my qualitative requirements (pre-processing, data clean up, etc.).

The rendering of this image is a bi-color version obtained by combining two different narrowband filters whose wavelengths are different from one another: Oxygen III (500 nm) & Hydrogen alpha (650 nm). The details of the supernova remnants are mind-blowing. I took a particular care to enhance both the oxygen III and hydrogen-alpha emissions while minimizing the overwhelming effects of the stars.
