Description

Vela Supernova Remnant in HOO with RGB stars

What started as a single shot rolled into this 18 panel mosaic!

This is by far the biggest mosaic I have done so far and also my first attempt at this target. Lots of work but lots of fun as well.

This took me about 18 nights over 2 months to capture due to the weather here in Melbourne.

The mosaic resolution is 18000x12000

With an image of that size, processing was quite a challenge and took a lot of time as each step would require a lot more time than normal process.

The size of this object cannot be underestimated, it is absolutely enormous!

With the colours and the framing in this picture, I can't help but to see Superman.. do you see it? ;)

From wiki:

The Vela supernova remnant is a supernova remnant in the southern constellation Vela. I

ts source Type II supernova exploded approximately 11,000–12,300 years ago (and was about 800 light-years away).

The association of the Vela supernova remnant with the Vela pulsar, made by astronomers at the University of Sydney in 1968,=10.5px was direct observational evidence that supernovae form neutron stars.

The Vela supernova remnant includes NGC 2736. It also overlaps the Puppis A supernova remnant, which is four times more distant.

Both the Puppis and Vela remnants are among the largest and brightest features in the X-ray sky.The Vela supernova remnant (SNR) is one of the closest known to us.

The Geminga pulsar is closer (and also resulted from a supernova), and in 1998 another near-Earth supernova remnant was discovered, RX J0852.0-4622, which from our point of view appears to be contained in the southeastern part of the Vela remnant.

One estimate of its distance puts it only 200 parsecs away (about 650 ly), closer than the Vela remnant, and, surprisingly, it seems to have exploded much more recently, in the last thousand years, because it is still radiating gamma rays from the decay of titanium-44. This remnant was not seen earlier because in most wavelengths, it is lost because of the presence of the Vela remnant.
