The Vela Supernova Remnant is a large and complex structure in the southern sky that is the result of a supernova explosion that occurred approximately 11,000-12,000 years ago. It is located in the constellation Vela, which is Latin for “the sails,” and is one of the closest and best-studied supernova remnants.

The Vela SNR is estimated to be about 800 light-years away from Earth and spans an area of approximately 8 degrees in the sky, making it one of the largest objects visible to the naked eye.

I have chosen the heart of the Vela as a subject for its high level of structural detail in this mega structure.

I have captured about 20h of data with RGB for the stars and Ha, Oiii and Sii for narrowband. Ha is map to Red, Oiii to blue and Sii to light blue which make the sulphur contribution appear purple in the image.

To give you a better idea of the size of the structure here is where it is located check I have marked it on this image below. This is an 18 panel mosaic of this supernova remnant I took in 2022.
