Vela Supernova Remnant

A two-part mosaic of the Vela Supernova Remnant in Bi-Color Narrowband Hydrogen-alpha (mapped to Red) and Triple-Ionized Oxygen (OIII mapped to Green and Blue)

 

Vela Supernova Remnant is the remains of a star that exploded about 800 light years away, around 12,000 years ago, creating a vast, intricate cloud of gas and radiation, appearing to us now as roughly the size of 16-full moons, but far too dim to see anything-of without a largish telescope.

 

This 2-part mosaic was a total of about 45 hours of exposures with a 250mm GSO RC telescope.
